Abstract
Focuses on a finite element computational model for the Timoshenko bea m which is idealized as an elasto-plastic-damage medium governed by Le maitre's continuum damage mechanics (CDM) model for ductile fracture. Response under monotonically increasing loading does not show any devi ation from elasto-plastic simulation, However, a marked difference in the residual stress field is noted by virtue of the unloading phase, i n which the CDM model allows far stiffness degradation in contrast to classical elasto-plasticity which requires unloading at the (frozen) i nitial stiffness of the material.
