摘要

In this paper, topology optimization of elasto-plastic structures is investigated using the evolutionary structural optimization (ESO) method. In order to maximize the stiffness for a given amount of material, the total strain energy density of an element is used as the rejection criterion. Several 2-D and 3-D examples are presented to demonstrate the capability and effectiveness of the present optimization process. Results show that the present ESO method produces different topology designs from those of the traditional linear ESO method and the present optimal designs result in significantly improved load-carrying capacities. Finally, the topologies are presented using a smoothing technique.
