Abstract :
A complex finite strip method of analysis that includes inelasticity is described.the finite strip displacement functions are augmented with so-called bubble functions,which are extra modes associated with internal or nodeless degrees-of-freedom.it is shown that the use of bubble functions significantly improves the convergence of the inelastic finite strip method.the analytical procedure is then used to study the inelastic local buckling of plates in compression and shear, stiffened plates in compression and l-section beams in shear
