Abstract

A series of tests on scaled quasi-isotropic laminates have been modelled using finite element analysis to predict failure. Examination of the failed test specimens showed significant influence of delamination on the final failure. Initially the Virtual Crack Closure Technique (VCCT) was used to determine edge delamination stresses but agreement with test results was poor. An interface element was introduced to model the delaminations and their interaction with matrix cracks. In all but the smallest specimens, which were dominated by fibre failure, very good correlation was achieved.
