Progressive Damage Simulation of Thick Viscoelastic Laminate With Homogenization Technique Conference Paper uri icon

abstract

  • Abstract For a thick viscoelastic laminate, modeling of individual lamina and cracks is impractical because it requires huge computational expense. In our previous study, homogenization techniques for undamaged viscoelastic sublaminates were developed. We have also developed a technique for the progressive damage analysis of viscoelastic laminates with transverse matrix cracks. Homogenization at the lamina level was used to account for damage. The method is based on a numerical proof that the variation of the stress state of a viscoelastic laminate depends on the instantaneous crack density not on the time-history of cracking. Combining these two methods, we developed a very efficient multi-level homogenization technique for progressive damage analysis of a thick viscoelastic laminate with cracks. This method is very efficient and accurate.
