"This text provides a thorough introduction to the subject of polymers from a mechanical engineering perspective, treating stresses and deformations in structural components made of polymers. Three themes are developed. - First, the authors discuss the time-dependent response of polymers and its implications for mechanical response. Secondly, descriptions of mechanical response are presented for both time-dependent and frequency-dependent material properties. - Finally, the stress-strain-time relation is applied to determine stresses and deformations in structure. - "With numerous examples and illustrations, this book will help advanced undergraduate and graduate students, as well as practicing mechanical engineers, make optimal and effective use of polymeric materials."--BOOK JACKET
