A transient nonlinear finite element framework and implementation of coupled electro-chemo-mechanics of polyelectrolyte hydrogels
Bibekananda Datta, Brandon K. Zimmerman, Thao D. Nguyen
Polyelectrolyte (PE) hydrogels exhibit complex behavior characterized by large mechanical deformations, nonlinear stress response, solvent transport, and ion diffusion. The interpl…

A finite viscoelastic constitutive model for low to high strain rate response of elastomers with application of strain rate-induced glass transition
Bibekananda Datta, Sushan Nakarmi, Nitin P. Daphalapurkar
Amorphous elastomers exhibit significant rate-stiffening and unique viscous flow characteristics across a wide range of strain rates, often undergoing glass transition above a stra…

A Data-Driven Approach to Geometric Modeling of Systems with Low-Bandwidth Actuator Dynamics
Siming Deng, Junning Liu, Bibekananda Datta +5
It is challenging to perform system identification on soft robots due to their underactuated, high-dimensional dynamics. In this work, we present a data-driven modeling framework,…
