Plasticity Encoding for Accelerated Mechanical Properties Prediction

New publication details a novel ML-based method for accelerated mechanical properties prediction from encoding and mapping metal plasticity. Encoding metal plasticity captured from high-resolution digital image correlation (DIC) can be leveraged to predict a wide range of monotonic and cyclic macroscopic properties of metallic materials. To capture the spatial heterogeneity of plasticity that develops in …

Plastic deformation at cryogenic temperatures

Explore our group’s latest publication in Acta Materialia, led by Dhruv Anjaria. Our research focuses on the plasticity of a FCC material at cryogenic temperatures (liquid nitrogen and helium temperatures). We discovered a novel deformation mechanism where deformation twinning and slip compete, causing the delocalization of plastic deformation, which impacts the properties of metallic materials …
