Abstract
A study of the strain redistribution around holes in two different cross-woven ceramic matrix composites is presented. The strain redistribution around holes in C-f/SiCm and SiCf/SiCm has been measured experimentally under plane stress conditions. Using micro-mechanics and Continuum Damage Mechanics, and an identification procedure based on a uni-axial tensile test and a shear test the strain redistribution around a hole or a notch due to matrix cracking can be predicted. Damage due to fiber breakage is not included in the model. Initial matrix damage in the C-f/SiCm material has to be implemented to provide better agreement between experiments and modelling. The cross-woven structure is modelled as a laminate.
