ELASTOPLASTIC ANALYSIS WITH LIMITED PLASTIC-DEFORMATIONS AND DISPLACEMENTS

This paper presents solution methods for elastoplastic and shakedown a nalysis of linearly elastic, perfectly plastic bodies for which the co nventional classical formulations of these problems are completed by c onstraints on overall plastic deformation and elastoplastic displaceme nt. The methods are described in terms of nonlinear mathematical progr amming and provide solutions when the plastic reserves of the body are not fully exhausted, and the plastic performance and the plastic defo rmations are controlled. Application of the method is illustrated by a n example.
