Numerical Analysis Of Distributed Intial Imperfection And Angular Dent On Square Plates
The aim of the work is to numerically analyses the various dent parameters dent length (l), dent width (w), dent
depth (Ld) and dent angle () on ultimate strength of thin dented square plates with rectangular dent at two different angles
with distributed initial imperfections under uni-axial compressive load in a simply supported boundary conditions. Ultimate
strength of the dented plate is determined by the steady state non-linear FE analysis including both material and geometrical
non linearities. Four equations have been generated to estimate the ultimate strength as a function of plate slenderness and
