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;…
Comparison of simulated and measured grain volume changes during grain growth
Xiaoyao Peng, Aditi Bhattacharya, S. Kiana Naghibzadeh +4
The three-dimensional microstructure of Ni, observed after five annealing intervals, was compared to simulations of grain growth using the threshold dynamics method with the assump…
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…
