Abstract
Longitudinally stiffened glass fiber reinforced polymer (GFRP) stiffened composite plates with and without overlap at various locations and directions are analyzed under axial and lateral loading using ABAQUS to find the critical location and optimum length of overlap. Ultimate load, maximum displacements and failure modes of composite plates with and without overlap obtained from finite element analysis are compared with experimental results (Priyadharshani et al., 2017). Studies are carried out on longitudinally stiffened GFRP composite plates with overlap perpendicular to stiffeners and parallel to stiffeners for both axial and lateral loading cases. Comparisons are drawn for various composite plates under different loading combinations. Analysis of stiffened composite plates with and without overlap is carried out to determine the critical location of overlap and overlap length required for restoring strength and stiffness loss. The optimum overlap length for all the specimens with axial compressive loads is equal to thickness of the plate. The optimum overlap lengths for all the specimens with lateral loads obtained is 2 t (except the specimens with overlap at one third and two third locations).
