Graph networks fracture mechanics
WebAug 1, 2024 · Fracture networks of all types and scales can be characterised in terms of their topology rather than their geometry. In two-dimensions, a fracture network can be seen as a system of branches and nodes. These elements form a planar graph, since all crossings of fractures are nodes. WebJun 1, 2024 · We present the application of a class of deep learning, known as Physics Informed Neural Networks (PINN), to inversion and surrogate modeling in solid mechanics. We explain how to incorporate the momentum balance and constitutive relations into PINN, and explore in detail the application to linear elasticity, and illustrate its extension to …
