Abstract:
In this study, the effects of edge contact-frictional force imposed by the machine heads on the distribution of stress state prior to buckling of plates are investigated. A contact-friction interface element is included in the pre-buckling analysis which considers the possibility of slip between the machine heads and the plate. All analyses are performed using the incremental theory of plasticity in which the formulations given by Ramberg-Osgood and Richard are implemented to calculate the tangent modulus. The pre-buckling stress states are used to determine the buckling stresses. In the buckling formulation of the plate, an element stiffness based on Hermitian interpolation function is included. The buckling stresses are compared with those of the test results and the closed form solutions available in the literature. The effect of edge boundary imperfections are also considered in this study.
