Abstract Scope |
Denoising diffusion probabilistic models, a new family of deep generative models, have been used for microstructure reconstruction and generation. This study focuses on the inverse design of architected composite materials to achieve desired mechanical behavior under multi-directional loading using a conditional diffusion model. By leveraging this model, predicting and realizing complex mechanical behaviors becomes feasible. The approach guides the microstructural design of composite materials based on conditional labels of target mechanical responses, ensuring systematic control to meet performance criteria. Training and testing on the mechanical MNIST dataset showed that the strain energy and reaction forces of the generated microstructures align with desired behaviors. These findings underscore the potential of inverse design in creating materials with tailored properties, advancing applications from aerospace to biomedical engineering. This research establishes a new paradigm in developing high-performance composite materials using conditional diffusion models. |
