Subject and Keywords:
A new computational delamination method using Damage Mechanics of composite laminates is proposed. A laminate is modeled as a stacking sequence of homogeneous layers and interlaminar interface. Both components are subject to damage. Deterioration such as fiber rupture, matrix and interface degradation are introduced at an intermediate level, which is called the meso-level. Damage is assumed to be uniform throughout the ply thickness. This makes it possible to avoid the main computational difficulties such as mesh dependency. For delamination analysis around a hole, an efficient numerical treatment is proposed to solve nonlinear (constitutive law) three-dimensional (edge effects) problems at a reasonable cost. Simulations are given.
