Single and Multi-material Topology Optimization of Continuum Structures: ABAQUS Plugin

This research addresses the need for versatile topology optimization techniques capable of optimizing both single and multi-material designs. The extended Python code incorporates the modified Bi directional Evolutionary Structural Optimization (BESO) algorithm and a material interpolation scheme to enhance its capabilities. Engineers and designers can utilize this improved approach to optimize the performance of structures, especially in the context of multi-material configurations. To increase its practicality, the code is converted into ABAQUS plugin, seamlessly integrating it with the widely used finite element analysis software. Validation examples, conducted in the ABAQUS environment, demonstrate the compatibility and accuracy of the code. This research provides an efficient and accurate solution for topology optimization, addressing the demands of multi-material designs in various engineering applications. Examples of such applications include lightweight design in automotive and aerospace industries, customized implants in biomedical engineering, and optimal material distribution in architectural structures.
