In the process of manufacture and use, the composite stiffened plate will degrade and produce different types of cracks and damage, which limits its application. Therefore, it is significant to study the composite stiffened plate with cracks. Three-dimensional Hashin failure criterion and the gradual damage model of TAN parameter degradation are applied to simulate composite stiffened plate with long crack under uniaxial compression and pure shear load. The effects of crack angle on the ultimate compressive strength, shear strength and progressive damage of composite stiffened plates were investigated. The results show that the effect of crack angle on the compression performance of the stiffened plate is not simply linear, but the effect on the shear performance of the stiffened plate is more complicated, and The effect of crack angle on shear behavior is also related to the sequence of layer.
