Concept of Composite:
Fibers or particles embedded in matrix of another material are the best example of modern-day
composite materials, which are mostly structural.
Laminates are composite material where different layers of materials give them the specific
character of a composite material having a specific function to perform. Fabrics have no matrix
to fall back on, but in them, fibers of different compositions combine to give them a specific
character. Reinforcing materials generally withstand maximum load and serve the desirable
properties.
Further, though composite types are often distinguishable from one another, no clear
determination can be really made. To facilitate definition, the accent is often shifted to the levels
at which differentiation take place viz., microscopic or macroscopic.

Optimizing the Shape of Mechanical Elements and Structures
Shirley Seireg, «Optimizing the Shape of Mechanical Elements and Structures»
CRC | ISBN: 0824795555 | 1997-01-02 | DJVU | 616 pages | 12.23 MB
Introduces a wide variety of practical approaches to the synthesis and optimization of shapes for mechanical elements and structures-emphasizing the simplest methods possible for achieving the best results without mathematical complexity, especially computer solutions. Provides in-depth case studies of structures subjected to different types of static and dynamic loading, including load-bearing structures with arbitrary support conditions, rotating disks, layered structures, pressure vessels, elastic bodies, and structural elements subjected to impulsive loading.

The purpose of the Structures Notebook is to explain, in the simplest possible terms, about the structure of 'things', and to demonstrate the fact that everything you see and touch, live in and use, living and man-made, has a structure which is acted upon by natural forces and reacts to these forces according to its form and material.
The Structures Notebook was originally written by Tony Hunt as a brief teaching aid for students at the Royal College of Art who had very little, if any, knowledge of physics or structural behaviour. It has now been expanded, and with this second edition, updated, into a more comprehensive book while retaining a simple visual and non-mathematical approach to structures.
The book is divided into seven main sections, in a logical sequence, and is written in simple language. Each section, related to its text, has a comprehensive set of hand-drawn sketches which show, as simply as possible, what the text is about. The book is almost totally non-mathematical since the author believes very strongly that structural behaviour can be understood best by diagrams and simple descriptions and that mathematics for the majority of people interested in design is a barrier. The design of structures is a combination of art and science and to achieve the best solution, concept should always come before calculation.
* Includes a new chapter with twelve further inventive solutions from well-known engineers
* Hundreds of illustrations communicate a clear understanding of the subject, without mathematics
* Comprehensive coverage of key information, with examples and insights from this influential structural engineer

Modeling of Creep for Structural Analysis
Publisher: Springer | Pages: 230 | 2007-05 | ISBN: 3540708340 | PDF | 5 MB
Creep Modeling for Structural Analysis" develops methods to simulate and analyze the time-dependent changes of stress and strain states in engineering structures up to the critical stage of creep rupture. The principal subjects of creep mechanics are the formulation of constitutive equations for creep in structural materials under multi-axial stress states; the application of structural mechanics models of beams, plates, shells and three-dimensional solids and the utilization of procedures for the solution of non-linear initial-boundary value problems. The objective of this book is to review some of the classical and recently proposed approaches to the modeling of creep for structural analysis applications as well as to extend the collection of available solutions of creep problems by new, more sophisticated examples.
In Chapter 1, the book discusses basic features of the creep behavior in materials and structures and presents an overview of various approaches to the modeling of creep. Chapter 2 collects constitutive models that describe creep and damage processes under multi-axial stress states. Chapter 3 deals with the application of constitutive models to the description of creep for several structural materials. Constitutive and evolution equations, response functions and material constants are presented according to recently published experimental data. In Chapter 4 the authors discuss structural mechanics problems. Governing equations of creep in three-dimensional solids, direct variational methods and time step algorithms are reviewed. Examples are presented to illustrate the application of advanced numerical methods to the structural analysis. An emphasis is placed on the development and verification of creep-damage material subroutines inside the general purpose finite element codes.

Geologic Hazards: A Field Guide for Geotechnical Engineers
Geologic hazards pose the greatest threat to human safety for any geotechnical undertaking, but it is ultimately the engineer's ability to recognize and cope with these hazards that will determine the safety of life and property. Armed with Geologic Hazards: A Field Guide for Geotechnical Engineers you will be able to properly recognize, understand various geologic hazards, and provide safe and economical construction. Eminent expert Roy E. Hunt thoroughly examines the potential for slope failures, earthquakes, ground subsidence, collapse, and expansion. Using a clear conceptual approach, he explains what measures are available to minimize or eliminate the risks associated with each of these geologic hazards.
The book sets forth the basis for recognizing, understanding, and treating geologic hazards, using general concepts rather than rigorous mathematical analyses. The author covers the prediction of slope failures through recognition of geologic and other factors that govern failure, the treatment of slopes that are potentially unstable and pose a danger to some existing development, the design and construction of stable cut slopes and sidehill fills, and the stabilization of failed slopes. He provides the foundation for determining the potential for surface movements and for preventing or controlling their effects. A section on earthquakes summarizes and links all of the aspects of earthquakes including their causes, characteristics, and surface effects. It provides a thorough grounding in how to recognize hazard potential and minimize the consequences.
There is no field within geotechnical engineering in which the state of the art is changing so rapidly. Providing the latest information, this resource is a useful tool for designing new projects and redesigning old ones.
