✦ Synopsis

models are proposed to predict the mixed-mode fracture of notched composite laminates subjected to uniaxial and multiaxial loading. The basic elastic, strength properties and a characteristic length are utilized by these models. The characteristic length is determined differently for the two models. A first-ply-failure criterion or a fiber failure criterion is applied in conjunction with the models. It was found that failure of notched laminates for the fiber dominated mode, matrix dominated mode or a combination of the two modes under different loading conditions can all be predicted very well and the characteristic length is independent of loading conditions.
