Abstract:
The orthogonal cutting of composite T800/M21 is simulated using a dynamic explicit analysis. To simulate the cavity behavior in the inner ninetydegree plies, a three-dimensional model with an elastic homogenous damageevolving material is used. Modified Matzenmiller failure criteria are applied to predict damage initiation and evolution in the studied structure. The used approach consists on combining a parametric modeling, based on an adequate prediction strategy, with a damage delaying procedure. A significant qualitative match between experimental results and numerical calculations is found. The outlined cavity aspect has been successfully retraced. Transverse shear damage and breakage in fiber direction are responsible of the failure of elements in the zerodegree plies. Each damage mode contribution to the collapse of the composite is discussed.
