Abstract:
Reinforcement structures involve the use of advanced materials, optimization techniques, and computational methods to enhance the strength and performance of components. Modern multi-material three-dimensional printers can manufacture reinforced structures with complex topologies. We present a computational design method to reinforce an object through the Solid Isotropic Material with a Penalization method decreasing the structure's compliance by pinpointing particular areas in the structure that need strengthening while preserving the initial dimensions of the model. We demonstrate mathematically the typical topology optimization approach remains effective when substituting voids with an alternative material. The rationale of our approach is to utilize the Solid Isotropic Material with a Penalization for modelling a two-material structure, in which the second material replaces the voids indicated by the Solid Isotropic Material with a Penalization process. We apply our approach to a two-dimensional cantilever beam and perform a mesh convergence study to confirm our method's validity. Moreover, we compare the displacement and von Mises results of a baseline beam that has only a weak material and a reinforced beam that has two materials (weak and strong materials). The results indicate that von Mises stress is higher when the maximum displacement is lower in the reinforced beam.
