Abstract

In this work, a numerical tool was developed to take into account the fundamental phenomena that rule the compressive behaviour of composite panels with trough-the-width and embedded delaminations.

The Modified Virtual Crack Closure Technique (MVCCT) was applied to evaluate the delamination growth phenomenon. Stable and unstable propagations was considered in our analyses; the latter required some modifications in the numerical non-linear algorithm used in the analyses.

First of all, a comparison with experimental data was carried on to test the effectiveness of the numerical tool; then a sensitivity analysis was introduced to underline the influence of trough-the-width and embedded delamination's position along the thickness and their growth on the compressive behaviour.
