Phase-Field Finite Deformation Fracture with an Effective Energy for Regularized Crack Face Contact
Maryam Hakimzadeh, Vaibhav Agrawal, Kaushik Dayal +1
Phase-field models are a leading approach for realistic fracture problems. They treat the crack as a second phase and use gradient terms to smear out the crack faces, enabling the…
Multiband homogenization of metamaterials in real-space: Higher-order nonlocal models and scattering at external surfaces
Kshiteej Deshmukh, Timothy Breitzman, Kaushik Dayal
This work develops a dynamic homogenization approach for metamaterials. It finds an approximate macroscopic homogenized equation with constant coefficients posed in space and time;…
Predicting Peak Stresses In Microstructured Materials Using Convolutional Encoder-Decoder Learning
Ankit Shrivastava, Jingxiao Liu, Kaushik Dayal +1
This work presents a machine learning approach to predict peak-stress clusters in heterogeneous polycrystalline materials. Prior work on using machine learning in the context of me…
