Instability and Failure in Ductile Solids with Regular Microstructures

Abstract

The work accomplished in this project consists of the following contributions: (a) onset-of-failure surface calculations for finitely strained continua with periodic microstructures - which have either voids or rigid inclusions - and which are subjected to arbitrary loading in plane strain (2D), (b) failure surfaces for composites under combined axial and shear loading and comparison of the calculations with experimental results carried out at the University of Texas at Austin, (c) onset-of-failure surface calculations for finitely strained continua with prismatic microstructures-but arbitrary 2D cross section of the unit cell - which are subjected to arbitrary 3D loading and finally (d) development of a consistent criterion for the onset of failure in rate sensitive materials.
