This final report describes research activities conducted during the course of the grant. They were concerned generally with the analysis of cracks in particulate and fibrous viscoelastic media and the effect of cracks on the mechanical behavior of composites. The work is presented in five sections 1 Elastostatic Fields in a Crack Tip Neighborhood-Measurements and Uniqueness 2 On the Mechanical Behavior of Solid Propellant under Transient Temperatures 3 Some Viscoelastic Crack Growth Relations for Orthotropic and Prestrained Media 4 A theory of Time-Dependent Bonding for Viscoelastic Media and 5 A method for Predicting Crack Growth in nonhomogeneous Viscoelastic Media. Only abstracts and conclusions are given in the last three sections as the studies were previously published in separate reports. Author
