A generalized machine learning framework for brittle crack problems using transfer learning and graph neural networks

no code implementations22 Nov 2022 Roberto Perera, Vinamra Agrawal

The new framework, ACCelerated Universal fRAcTure Emulator (ACCURATE), is generalized to a variety of crack problems by using a sequence of TL update steps including (i) arbitrary crack lengths, (ii) arbitrary crack orientations, (iii) square domains, (iv) horizontal domains, and (v) shear loadings.
