Three Dimensional Simulation for Extension of Interlaminar Delamination in Laminated Composite

抄録

An effective numerical algorithm is developed to simulate extension of the interlaminar delamination in a laminated composite based on the three dimension al finite element method. As use of the conjugate gradient or ICCG method to solve a system of linear equations minimizes occupation of memory space in computation, matrix of linear equations is made to be symmetric for contact problems on the delaminated interface of the composite. The extension of the interlaminar delamination is simulated in a cross-ply laminated composite with four layers under concentrated load on the center of the composite. Distribution of deflection on the laminated composite with the delamination is also shown graphically.
