Instabilities and Phase Transformations in Architected Metamaterials: a Gradient-Enhanced Continuum Approach
Sarvesh Joshi, S. Mohammad Mousavi, Craig M. Hamel +4
Architected metamaterials such as foams and lattices exhibit a wide range of properties governed by microstructural instabilities and emerging phase transformations. Their macrosco…

Uncertainty quantification of neural network models of evolving processes via Langevin sampling
Cosmin Safta, Reese E. Jones, Ravi G. Patel +4
We propose a scalable, approximate inference hypernetwork framework for a general model of history-dependent processes. The flexible data model is based on a neural ordinary differ…
