A METHOD FOR LARGE DEFLECTION INELASTIC ANALYSIS OF PLATE GRILLAGES UNDER NORMAL AND AXIAL LOADS

A method for analyzing plate grillages subjected to normal and axial loads was developed. Elastoplastic range and large deformations are considered. The grillage equations were formulated from the general differential equations of plates and beams and a collocation type approach was employed for solving these equations. Due to the geometrical and material non-linearity of the problem it was necessary to employ a search technique in arriving at an answer. The feasibility of the method was demonstrated by analyzing a rectangular plate and a plate grillage with two transverse and two longitudinal stiffening beams. (Author)
