Deformation Driven Suction Cups: A Mechanics-Based Approach to Wearable Electronics Open
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 critical for these applications, it remains challenging due …

On recovering intragranular strain fields from grain-averaged strains obtained by high-energy X-ray diffraction microscopy Open
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. Referred to as either high-energy X-ray diffraction microscopy…

Learning constitutive relations from experiments: 1. PDE constrained optimization Open
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 constitutive relations from experiments as an indirect inverse…

Stability and post-bifurcation of film-substrate systems Open
Morphological instabilities in soft solids with free surfaces lead to an array of deformation modes including wrinkling, creasing, folding and ridge localization. While homogeneous systems tend to form creases, stiff films over soft substr…

Optimal Design of Responsive Structures Open
With recent advances in both responsive materials and fabrication techniques it is now possible to construct integrated functional structures, composed of both structural and active materials. We investigate the robust design of such struc…
