Demonstrates the simplicity and effectiveness of Mathematica as the solution to practical problems in composite materials
Designed for those who need to learn how micromechanical approaches can help understand the behaviour of bodies with voids, inclusions, defects, this book is perfect for readers without a programming background. Thoroughly introducing the concept of micromechanics, it helps readers assess the deformation of solids at a localized level and analyse a body with microstructures. The author approaches this analysis using the computer algebra system Mathematica, which facilitates complex index manipulations and mathematical expressions accurately.
The book begins by covering the general topics of continuum mechanics such as coordinate transformations, kinematics, stress, constitutive relationship and material symmetry. Mathematica programming is also introduced with accompanying examples. In the second half of the book, an analysis of heterogeneous materials with emphasis on composites is covered.
Takes a practical approach by using Mathematica, one of the most popular programmes for symbolic computation
Introduces the concept of micromechanics with worked–out examples using Mathematica code for ease of understanding
Logically begins with the essentials of the topic, such as kinematics and stress, before moving to more advanced areas
Applications covered include isotropic materials, plates and shells and thermal stress
Features a problem and solution section on the book’s companion website, useful for students new to the programme
Seiichi Nomura, The University of Texas at Arlington, USA Professor Nomura studied his BSc and MSc at the University of Tokyo, Japan before completing his PhD at the University of Delaware. He is now Professor in the Department of Mechanical and Aerospace Engineering at the University of Texas at Arlington, USA. Professor Nomura has undertaken research on the analysis of mechanical and thermal properties of heterogeneous materials including composite materials and functionally graded materials (FGMs) and has published extensively in this area.
