Abstract

A new method for topology optimization of continuum structures modeled by finite elements is presented. The objective of the research presented in this paper is to build a flexible and mesh-independent topology tool. This is accomplished by creating a GA implementation that defines functional components, referred to as masks that have standard geometric shapes such as circles, ellipses, or rectangles. When applied to a finite element model, all the elements that are covered by these masks are removed. The removal of elements can be performed without causing any singularities by using the birth and death capability available in the ANSYS software (SWANSON Ltd.). The method proved to be efficient, providing meaningful and easily manufacturable topologies for a variety of loadings and analysis options such as dynamic and static loads. Two different examples of structures are provided.
