Programs ECT and RSC apply a special
plate theory, developed specifically for nonlinear elastic material
like paper, to determine the critical buckling strain of a
plate structure and the stress in each structure element. The solution
procedure enables plates to be connected along common boundaries in a
boundary element analysis with only a small number of degrees-of-freedom
needing to be considered. A postbuckling theory, whose constants are a
function of the input to PPR, predicts structure
strength from the boundary element output.
