MATLAB Implementation of the Proportional Topology Optimization Method

The novel topology optimization technology employs a non-gradient methodology that distributes material based on proportional relationships, effectively solving complex structural optimization challenges. By bypassing the need for gradient information, it streamlines the process for addressing both stress-constrained and minimum compliance problems. Two specialized MATLAB programs have been developed to tackle these distinct scenarios, ensuring a straightforward implementation alongside robust computational efficiency. Extensive testing using two-dimensional numerical examples has demonstrated that the system achieves efficiency and accuracy on par with traditional gradient-based approaches.
