Abstract:

A finite element technique is presented for the plastic analysis of structures subjected to out-of-plane bending, alone or in combination with in- plane membrane stresses. The method makes uses of a linear matrix equation of finite element analysis, formulated to include the effect of initial strains. Application of the procedure is made to beam and arch structures in the presence of both types of nonlinearity, and to rectangular plates for which material nonlinearity alone is present.
