Book Description
Although there are several books in print dealing with elasticity, many focus on specialized topics such as mathematical foundations, anisotropic materials, two-dimensional problems, thermoelasticity, non-linear theory, etc. As such they are not appropriate candidates for a general textbook. This book provides a concise and organized presentation and development of general theory of elasticity. This text is an excellent book teaching guide. Contains exercises for student engagement as well as the integration and use of MATLAB Software Provides development of common solution methodologies and a systematic review of analytical solutions useful in applications of

Book Description
In this study, finite element analysis (FEA) is used to study the effect of surface roughness on the stresses generated during bending of micro/nanoscale cantilever beam structures. Surface roughness variation is generated by controlling roughness parameters of a Gaussian height distribution and incorporating this distribution onto the top surface of a beam using the FEA code, ANSYS. Silicon beams with varying surface roughness, width and thickness are modeled with a bending load subject to the free end of the cantilever beam. It is observed that the maximum (tensile) bending stress increases with an increase in root mean square (RMS) levels of surface roughness. Results also showed that up to a certain level of roughness, the maximum tensile stress occurs at the geometric discontinuity (GD) at the base of the cantilever. Beyond this critical RMS roughness, maximum stress occurs at the location of maximum peak-to-valley (MPV) distance. Decreasing beam dimensions and increasing the radius of curvature of the GD enhances the effect of roughness on the stress levels. Simulation of a beam with surface roughness from an atomic force microscopy image of a surface micromachined cantilever beam showed that for the low roughness levels generated by this process, maximum stress occurs at the GD. This study demonstrates that surface roughness can affect stress levels in micro/nanoscale structures and will aid in predicting optimum surface roughness parameters for reliable mechanical behavior.

Book Description
Designed for a one-semester course in Finite Element Method, this compact and well-organized text presents FEM as a tool to find approximate solutions to differential equations. This provides the student a better perspective on the technique and its wide range of applications. This approach reflects the current trend as the present-day applications range from structures to biomechanics to electromagnetics, unlike in conventional texts that view FEM primarily as an extension of matrix methods of structural analysis. After an introduction and a review of mathematical preliminaries, the book gives a detailed discussion on FEM as a technique for solving differential equations and variational formulation of FEM. This is followed by a lucid presentation of one-dimensional and two-dimensional finite elements and finite element formulation for dynamics. The book concludes with some case studies that focus on industrial problems and Appendices that include mini-project topics based on near-real-life problems. Postgraduate/Senior undergraduate students of civil, mechanical and aeronautical engineering will find this text extremely useful; it will also appeal to the practising engineers and the teaching community.
