Topological optimization of plane elastic continuum with stress constraints

Cheng Gengdong;Zhang Dongxu(Research Institute of Engineering Mechanics,DUT)  
The paper studies the topology optimization of plane elastic continuum with stressconstraints.The external loads and supports are given.The optimum continuum to be designedhas uniform thickness distribution and minimizes material volume.By analyzing the specialdifficulty of topology optimization with truss example,the authors present a revised fully stressmethod which avoids continuous modification of design space and provides the mechanism toenable the element once deleted to reenter the structure.Numerical results illustrate thepromising performance of the method.
