Annual Scientific Report, 1 April 1980 thru 31 March 1981,

Abstract

This report summarizes progress on certain theoretical questions arising in the study of the fracture mechanics of linearly elastic and viscoelastic material. Specifically, two classes of problems are described: (1) Energy release rate calculations for a mode III elastic interface edge crack based on the M-conservation integral; and (2) A description of the dynamic stress field ahead of a steadily propagating semi-infinite crack in a general infinite viscoelastic body and in a viscoelastic layer of finite thickness. Both Mode I and Mode III deformations are considered. (Author)
