The book reviews the two features of the variational approach: its use as a universal tool to describe physical phenomena and as a source for qualitative and quantitative methods of studying particular problems.
Berdichevsky’s work differs from other books on the subject in focusing mostly on the physical origin of variational principles as well as establishing their interrelations. For example, the Gibbs principles appear as a consequence of the Einstein formula for thermodynamic fluctuations rather than as the first principles of the theory of thermodynamic equilibrium. Mathematical issues are considered as long as they shed light on the physical outcomes and/or provide a useful technique for the direct study of variational problems. In addition, a thorough account of variational principles discovered in various branches of continuum mechanics is given.
In this book, the first volume, the author covers the variational principles for systems with a finite number of degrees of freedom; the variational principles of thermodynamics; the basics of continuum mechanics; the variational principles for classical models of continuum mechanics, such as elastic and plastic bodies, and ideal and viscous fluids; and direct methods of calculus of variations.
Variational Principles of Continuum Mechanics: II. Applications
This book, the second volume, describes how the variational approach can be applied to constructing models of continuum media, such as the theory of elastic plates; shells and beams; shallow water theory; heterogeneous mixtures; granular materials; and turbulence. It goes on to apply the variational approach to asymptotical analysis of problems with small parameters, such as the derivation of the theory of elastic plates, shells and beams from three-dimensional elasticity theory; and the basics of homogenization theory. A theory of stochastic variational problems is considered in detail too, along with applications to the homogenization of continua with random microstructures.

Author: Leonid P. Lebedev, Michael J. Cloud, Victor A Eremeyev | Size: 2.07 MB | Format:PDF | Quality:Original preprint | Publisher: World Scientific Publishing Company | Year: May 18, 2010 | pages: 373 | ISBN: 9814313122, ISBN-13: 978-9814313124
The tensorial nature of a quantity permits us to formulate transformation rules for its components under a change of basis. These rules are relatively simple and easily grasped by any engineering student familiar with matrix operators in linear algebra. More complex problems arise when one considers the tensor fields that describe continuum bodies. In this case general curvilinear coordinates become necessary. The principal basis of a curvilinear system is constructed as a set of vectors tangent to the coordinate lines. Another basis, called the dual basis, is also constructed in a special manner. The existence of these two bases is responsible for the mysterious covariant and contravariant terminology encountered in tensor discussions.
A tensor field is a tensor-valued function of position in space. The use of tensor fields allows us to present physical laws in a clear, compact form. A byproduct is a set of simple and clear rules for the representation of vector differential operators such as gradient, divergence, and Laplacian in curvilinear coordinate systems.
This book is a clear, concise, and self-contained treatment of tensors, tensor fields, and their applications. The book contains practically all the material on tensors needed for applications. It shows how this material is applied in mechanics, covering the foundations of the linear theories of elasticity and elastic shells.
The main results are all presented in the first four chapters. The remainder of the book shows how one can apply these results to differential geometry and the study of various types of objects in continuum mechanics such as elastic bodies, plates, and shells. Each chapter of this new edition is supplied with exercises and problems most with solutions, hints, or answers to help the reader progress. An extended appendix serves as a handbook-style summary of all important formulas contained in the book.

Modern computer simulations make stress analysis easy. As they continue to replace classical mathematical methods of analysis, these software programs require users to have a solid understanding of the fundamental principles on which they are based.
Applied Mechanics of Solids is a powerful tool for understanding how to take advantage of these revolutionary computer advances in the field of solid mechanics. Beginning with a description of the physical and mathematical laws that govern deformation in solids, the text presents modern constitutive equations, as well as analytical and computational methods of stress analysis and fracture mechanics. It also addresses the nonlinear theory of deformable rods, membranes, plates, and shells, and solutions to important boundary and initial value problems in solid mechanics.
The author uses the step-by-step manner of a blackboard lecture to explain problem solving methods, often providing the solution to a problem before its derivation is presented. This format will be useful for practicing engineers and scientists who need a quick review of some aspect of solid mechanics, as well as for instructors and students.
Borrowing from the classical literature on linear elasticity, plasticity, and structural mechanics, this book:
* Introduces concepts, analytical techniques, and numerical methods used to analyze deformation, stress, and failure in materials or components
* Discusses the use of finite element software for stress analysis
* Assesses simple analytical solutions to explain how to set up properly posed boundary and initial-value problems
* Provides an understanding of algorithms implemented in software code
Complemented by the author’s website, which features problem sets and sample code for self study, this book offers a crucial overview of problem solving for solid mechanics. It will help readers make optimal use of commercial finite element programs to achieve the most accurate prediction results possible.

MATLAB code: PMM,PM,MM interaction curves for short columns of practically any shape
Size: 13 KB
The Matlab code for rectangular column interaction curve I posted last week is actually incorrect. The new one I post now can create the P-M-M, M-M, P-M interaction curves for short columns of practically any arbitrary shapes including openings. It has been extensively checked with spColumn v4.81 lastest version that shows excellent agreement.
4 main srcipt m files are included:
- RcolPMMall_1.m ---> rectangular column
- LcolPMMall_1.m ---> L-shaped column
- CcolPMMall_1.m ---> C-shaped column
- CcolPMMall_1w1O ---> C-shaped column with opening.
For typical regular shapes (rectangle, T, L, C, I, Z, Cross, regular polygons), the global coordinates (Xo,Yo,Xbo,Xbo) of the section & reinf bars can be readily built into the program. For an arbitray shape, they need to be specified.
Other files are supporting functions:
- polygeom.m: calculates area & centriodal coordinates of a polygon (this one I gleaned from the web; the rest are my own's)
- fcutpolygon1.m: cuts a polygon into 2 parts, retains & renumbers one of them for use (this is an essential part used to isolate the concrete compression block) + other minor .m files.
The program produces 4 graphs:
- geometry & reinf patern
- 3D P-M-M surface plot
- 2D Mx-My plot for a specified level of axial force P (that you can change)
- 2D P-M plot for a specified angle (GAMMA)of direction of biaxial bending moment
15 levels of P are used (changeable) ---> for some irregular shapes, the surface plot might look jagged in some places where the contours twist a lot.
Download link for Matlab m files below
Note: for correct results, corner points (Xo,Yo) of arbitary shapes are entered CLOCKWISE for main geometry & COUNTERCLOCKWISE for openings.

Theory and Analysis of Elastic Plates and Shells Author: J.N. Reedy | Size: Unknown MB | Format:PDF | Quality:Unspecified | Publisher: CRC Press | Year: 2006 | pages: 568 | ISBN: 978-0849384158
Because plates and shells are common structural elements in aerospace, automotive, and civil engineering structures, engineers must understand the behavior of such structures through the study of theory and analysis. Compiling this information into a single volume, Theory and Analysis of Elastic Plates and Shells, Second Edition presents a complete, up-to-date, and unified treatment of classical and shear deformation plates and shells, from the basic derivation of theories to analytical and numerical solutions.
Revised and updated, this second edition incorporates new information in most chapters, along with some rearrangement of topics to improve the clarity of the overall presentation. The book presents new material on the theory and analysis of shells, featuring an additional chapter devoted to the topic. The author also includes new sections that address Castigliano's theorems, axisymmetric buckling of circular plates, the relationships between the solutions of classical and shear deformation theories, and the nonlinear finite element analysis of plates. The book provides many illustrations of theories, formulations, and solution methods, resulting in an easy-to-understand presentation of the topics.
Like the previous edition, this book remains a suitable textbook for a course on plates and shells in aerospace, civil, and mechanical engineering curricula and continues to serve as a reference for industrial and academic structural engineers and scientists.
