Abstract

In this article the enhanced version of the damage mesomodel (DML) developed at LMT is validated with the simulations performed for intralaminar damage mechanisms using User MATerial subroutines in Abaqus Standard. The damage mechanisms validated in the present study include fibre breaking, diffuse damage and matrix microcracking. The efficacy of the proposed model is shown by a series of identification results on industrial test cases for T700/M21 material. The basic identification tests include 0° traction and compression, traction on [0m/90n] S laminates, monotonic and cyclic traction of [±45] 4S and [±67.5] 4S laminates. The validation test is carried out for a 32-ply carbon-epoxy laminate with an open hole in traction. It is seen that DML is successful in predicting the initiation and propagation of the above mentioned intralaminar damage mechanisms.
