The paper presents growth of embedded circular delamination in a thin laminate plate subjected to compressive loading. The following reinforcement combinations were considered: [0°//0°/0°], [0°//90°/0°] and [45°/-45°/-45°/45°//90°/45°/-45°/-45°/45°], where symbol//denotes the location of the delamination. The delamination growth was modeled with the use of MSC.MARC finite element commercial code. Two different modeling methods were used: a method based on the Virtual Crack Closure Technique (VCCT) and a method utilizing cohesive elements. In both methods the same regular mesh of 3D 8 node cuboidal elements was used to model the composite structure. It was found that both methods produced similar qualitative results with regard to the delamination geometry changes during loading. However, the method based on the VCCT produced more conservative results regarding the gradient of delamination growth.
