This book reminds students in junior, senior and graduate level courses in physics, chemistry and engineering of the math they may have forgotten (or learned imperfectly), which is needed to succeed in science courses.
The focus is on math actually used in physics, chemistry and engineering, and the approach to mathematics begins with 12 examples of increasing complexity, designed to hone the student's ability to think in mathematical terms and to apply quantitative methods to scientific problems. Detailed Illustrations and links to reference material online help further comprehension. The second edition features new problems, illustrations, and features expanded chapters on matrix algebra and differential equations.
• Use of proven pedagogical techniques developed during the author's 40 years of teaching experience
• New practice problems and exercises to enhance comprehension
• Coverage of fairly advanced topics, including vector and matrix algebra, partial differential equations, special functions and complex variables

The absence of computational methodology in some standards, and the lack of validation in others, thus justify the need for a research programme focusing on alternate load path analysis. The first step of the research therefore consists in investigating the various assumptions related to alternate load path analyses, as well as in comparing the available procedures, before launching into the development of new ones.

Laminated composite shells are frequently used in various engineering applications in the aerospace,
mechanical, marine, and automotive industries. This article follows a previous book and review articles
published by the leading author (Qatu, 2004, 2002, 1989, 1992, 1999 [1–5]). It reviews most of the
research done in recent years (2000–2009) on the dynamic behavior (including vibration) of composite
shells. This review is conducted with emphasis on the type of testing or analysis performed (free vibration,
impact, transient, shock, etc.), complicating effects in material (damping, piezoelectric, etc.) and
structure (stiffened shells, etc.), and the various shell geometries that are subjected to dynamic research
(cylindrical, conical, spherical and others). A general discussion of the various theories (classical, shear
deformation, 3D, non-linear etc.) is also given. The main aim of this review article is to collate the
research performed in the area of dynamic analyses of composite shells during the last 10 years, thereby
giving a broad perspective of the state of art in this field. This review article contains close to 200
references.

Dynamic elastic-plastic buckling of circular cylindrical shells under axial impact
Author: D. Karagiozova, Norman Jones | Size: 595 KB | Format:PDF | Quality:Unspecified | Publisher: Elsevier | Year: 1998 | pages: 30
Dynamic axisymmetric buckling of circular cylindrical shells struck axially by a mass is studied in order to clarify
the initiation of buckling and to provide some insight into the buckling mechanism as a transient process. It is
assumed that the material is elastic±plastic with linear strain hardening and displaying the Bauschinger eect. The
deformation process is analysed by a numerical simulation using a discrete model. Particular attention is paid to the
in¯uence of stress wave propagation on the initiation of buckling. It is found that the development of the buckling
shape depends strongly on the inertia properties of the striker and on the geometry of the shell. The theoretical
method is used to clarify some experimental data and good agreement is obtained with results on aluminium alloy
tubes.

A new energy and momentum conserving algorithm for the non-linear dynamics of shells
Author: J. C. Simo, N. Tarnow | Size: 1.27 MB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 1994 | pages: 23
A numerical time-integration scheme for the dynamics of non-linear elastic shells is presented that simultaneously and independent of the time-step size inherits exactly the conservation laws of total linear, total angular momentum as well as total energy. The proposed technique generalizes to non-linear shells recent work of the authors on non-linear elastodynamics and is ideally suited for long-term/large-scale simulations. The algorithm is second-order accurate and can be immediately extended with no modification to a fourth-order accurate scheme. The property of exact energy conservation induces a strong notion of non-linear numerical stability which manifests itself in actual simulations. The superior performance of the proposed scheme method relative to conventional time-integrators is demonstrated in numerical simulations exhibiting large strains coupled with a large overall rigid motion. These numerical experiments show that symplectic schemes often regarded as unconditionally stable, such as the mid-point rule, can exhibit a dramatic blow-up in finite time while the present method remains perfectly stable.

In this paper, a formulation for the dynamic stability analysis of functionally graded shells under harmonic axial loading is presented. A profile for the volume fraction is assumed and a normal-mode expansion of the equations of motion yields a system of Mathieu–Hill equations the stability of which is analyzed by the Bolotin’s method. The present study examines the effects of the volume fraction of the material constituents and their distribution on the parametric response, in particular the positions and sizes of the instability regions.
