Abstract
The paper is to study on dynamic response behavior of the stiffened delaminated composite plates considering failure process. A fonnula of element stiffuess and mass matrices for the composite laminated plate and beam are deduced by using the first-order shear defonnation theory. A damping model is constituted on the basis of Raleigh damping model in conjunction with Adams strain energy method (MSE). A delaminated constrained model and a virtual interface element are also developed for avoiding the overlap and penetration phenomenon between the upper and lower sub-laminates at the delamination region. The failure analysis method is established by Tsai's failure criterion and corresponding reduced stiffuess role. Some numerical examples show that the effects of frequency of dynamic load, delamination location, and reduction of structure stiffuess during the failure process dynamic behavior of the delaminated composite laminates are significant.
