This comprehensive text, featuring the integration of numerous theoretical developments, offers a complete, consistent description of the linear theory of the viscoelastic behavior of materials. Relevant theoretical formulations are derived from a continuum mechanics viewpoint, followed by discussions of problem-solving techniques.Topics cover viscoelastic stress strain constitutive relations, isothermal boundary value problems, thermoviscoelasticity, mechanical properties and approximate transform inversion, problems of a nontransform type, wave propagation, general theorems and formulations, nonlinear viscoelasticity, and nonlinear mechanical behavior. The text, which is ideal for graduate-level students, also includes Appendixes and an Index.
