A Survey of Topology Optimization of Continuum Structure

As the topology optimization of continuum structure can produce new configurations during the optimization,it is significant for automatic structure design.At present,the most commonly used topology optimization methods of continuum structure are: the homogenization method,variable thickness method,variable density method,evolutionary structural optimization method,level set method,independent continuous mapping method.Firstly,the development processes of above methods are systematically reviewed,their curr...
