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…
Deformation Driven Suction Cups: A Mechanics-Based Approach to Wearable Electronics
Seola Lee, Andrew Akerson, Roham Pardakhtim +8
Wearable electronics are emerging as essential tools for health monitoring, haptic feedback, and human-computer interactions. While stable contact at the device-body interface is c…
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…
Learning constitutive relations from experiments: 1. PDE constrained optimization
Andrew Akerson, Aakila Rajan, Kaushik Bhattacharya
We propose a method to accurately and efficiently identify the constitutive behavior of complex materials through full-field observations. We formulate the problem of inferring con…
