Principles of Composite Material Mechanics

Principles of Composite Material Mechanics covers a unique blend of classical and contemporary mechanics of composites technologies. It presents analytical approaches ranging from the elementary mechanics of materials to more advanced elasticity and finite element numerical methods, discusses novel materials such as nanocomposites and hybrid multiscale composites, and examines the hygrothermal, viscoelastic, and dynamic behavior of composites.

This fully revised and expanded Fourth Edition of the popular bestseller reflects the current state of the art, fresh insight gleaned from the author’s ongoing composites research, and pedagogical improvements based on feedback from students, colleagues, and the author’s own course notes.

New to the Fourth Edition

New worked-out examples and homework problems are added in most chapters, bringing the grand total to 95 worked-out examples (a 19% increase) and 212 homework problems (a 12% increase)

Worked-out example problems and homework problems are now integrated within the chapters, making it clear to which section each example problem and homework problem relates

Answers to selected homework problems are featured in the back of the book

Principles of Composite Material Mechanics, Fourth Edition provides a solid foundation upon which students can begin work in composite materials science and engineering. A complete solutions manual is included with qualifying course adoption.
