Abstract

Polystyrene cylinders and blocks were compressed with a variety of flat indentors until fracture occurred. The test cannot be interpreted solely by slip-line field theory, nor solely using Kendall's theory for the splitting of pre-cracked blocks of elastic material. A slip-line field analysis was made of the stress variation within the yielded zone beneath the indentor, then a boundary element analysis was made of the remaining cracked elastic region. This predicted stress intensity factors that are of the correct magnitude for the observed crack velocity.
