Learning viscoplastic constitutive behavior from experiments: II. Dynamic indentation
Andrew Akerson, Aakila Rajan, Daniel Casem +1
We continue the development of a method to accurately and efficiently identify the constitutive behavior of complex materials through full-field observations that we started in Ake…

Learning a potential formulation for rate-and-state friction
Shengduo Liu, Kaushik Bhattacharya, Nadia Lapusta
Empirical rate-and-state friction laws are widely used in geophysics and engineering to simulate interface slip. They postulate that the friction coefficient depends on the local s…

On recovering intragranular strain fields from grain-averaged strains obtained by high-energy X-ray diffraction microscopy
C. K. Cocke, A. Akerson, S. F. Gorske +2
We address an unusual problem in the theory of elasticity motivated by the problem of reconstructing the strain field from partial information obtained using X-ray diffraction. Ref…
