Abstract

In this study, an elastic-plastic stress analysis is carried out on simply supported and clamped cross-ply and angle-ply aluminum metal-matrix composite laminated plates with a circular hole. Classical lamination theory with first-order shear deformation theory is used for small deformations. The expansion of the plastic region and residual stress components are obtained on the upper and lower surfaces of the plates by using the finite element method. They are loaded on the upper surface transversely. Loading is gradually increased from the yield point of the plate by 0.0001 MPa at each load step. Load step numbers are chosen as 400, 600 and 800.
