Hi Kin Poh,

with /ANIM/SHELL/TENS/STRESS/ALL and /ANIM/SHELL/TENS/STRAIN/ALL keywords we can output the stress and strain for all plies in the composite material.

<?xml version="1.0" encoding="UTF-8"?>

Did you provide any failure cards for the composite (like /FAIL/LAD_DAMA, which describes the Ladeveze failure model for delamination (interlaminar fracture)).

If so, you can input /ANIM/SHELL/IPLY/MAXDA, /ANIM/SHELL/IPLY/DAM keywords in the engine file for extracting damage parameters.
