Resumo

Topological optimization looks for determining the ideal material distribution within a design domain (2D/3D) in order to optimize structural performance following imposed design constraints. This material distribution can vary continuously, resulting in complex shapes that are lighter than the original structure and take better advantage of material strengths. Incorporating multiple loads into topology optimization increases the complexity of the problem, as it requires simultaneous consideration of different types of loads and their interactions with the structure in problems that have several degrees of freedom. This can include the analysis of load combinations due to self-weight, other load combinations or even dynamic or thermal loads. This work aims to develop and implement a 3D structural topological optimization model that takes these multiple loads into account using MATLAB program language. Practical examples of optimization cases considering multiple loads are presented, as well as comparisons with existing results in the literature, in order to demonstrate the accuracy of the proposed algorithm.
