Abstract

In this paper, an elasto-plastic finite element analysis is carried out in woven steel fiber reinforced laminated thermoplastic composite plates subjected to transverse uniform loads. The laminated composite plate is clamped at all its edges. Numerical simulation is performed using the well-established commercial software ANSYS. To investigate the effects of ply number, orientation angle and bonding type for optimum design of fully clamped laminated composite plates, yielding loads and residual stresses are obtained. Three-load step is carried out for each analysis consecutively. The yielding transverse load is applied at first. Then, a series of load increments added until the load reaches "Yielding Load + 0.005 MPa". At the last step the external load is released to obtain the residual stress components.
