Abstract Scope |
Failure in materials often arises due to localized stress or strain concentrations, referred to as "stress hot spots". The likelihood of these hot spots forming is influenced by microstructural factors like local features, misorientations, among others, in relation to the applied load. Since these hot spots may lead to failure, it is advantageous to develop techniques to predict their formation based on the initial microstructural images. We describe a Convolutional Encoder-Decoder based approach to first model the elastic response in the form of stress fields simulated using Fourier transforms which can then be used to determine high-stress regions. The model is trained on local patches from synthetic microstructures generated using DREAM.3D and the results show that the Encoder-Decoder based approach can effectively learn spatial relations that may lead to hot spots. |
