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…
Optimal Structures for Failure Resistance Under Impact
Andrew Akerson
The complex physics and numerous failure modes of structural impact creates challenges when designing for impact resistance. While simple geometries of layered material are convent…
Optimal Design of Responsive Structures
Andrew Akerson, Blaise Bourdin, Kaushik Bhattacharya
With recent advances in both responsive materials and fabrication techniques it is now possible to construct integrated functional structures, composed of both structural and activ…
Effective continuum models for the buckling of non-periodic architected sheets that display quasi-mechanism behaviors
Connor McMahan, Andrew Akerson, Paolo Celli +2
In this work, we construct an effective continuum model for architected sheets that are composed of bulky tiles connected by slender elastic joints. Due to their mesostructure, the…
