A novel four-field mixed variational approach to Kirchhoff rods implemented with finite element exterior calculus
Jamun Kumar N, Bensingh Dhas, Arun R Srinivasa +2
A four-field mixed variational principle is proposed for large deformation analysis of Kirchhoff rods with a mixed FE approximations. The core idea behind the approach is to…

A mixed method for 3D nonlinear elasticity using finite element exterior calculus
Bensingh Dhas, Jamun Kumar, Debasish Roy +1
This article discusses a mixed FE technique for 3D nonlinear elasticity using a Hu-Washizu (HW) type variational principle. Here, the deformed configuration and sections from its c…
