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…
A mixed variational principle in nonlinear elasticity using Cartan's moving frame and implementation with finite element exterior calculus
Bensingh Dhas, Jamun Kumar N, Debasish Roy +1
This article offers a new perspective for the mechanics of solids using moving Cartan's frame, specifically discussing a mixed variational principle in non-linear elasticity. We tr…
FlowMesher: An automatic unstructured mesh generation algorithm with applications from finite element analysis to medical simulations
Zhujiang Wang, Arun R. Srinivasa, J. N. Reddy +1
In this work, we propose an automatic mesh generation algorithm, FlowMesher, which can be used to generate unstructured meshes for mesh domains in any shape with minimum (or even n…
Hierarchy of beam models for lattice core sandwich structures
Anssi T. Karttunen, J. N. Reddy
A discrete-to-continuum transformation to model 2-D discrete lattices as energetically equivalent 1-D continuum beams is developed. The study is initiated in a classical setting bu…
Nonlinear finite element analysis of lattice core sandwich plates
Praneeth Nampally, Anssi T. Karttunen, JN Reddy
A displacement-based, geometrically nonlinear finite element model is developed for lattice core sandwich panels modeled as 2-D equivalent single-layer (ESL), first-order shear def…
A general higher-order shell theory for compressible isotropic hyperelastic materials using orthonormal moving frame
Archana Arbind, J N Reddy, A R Srinivasa
The aim of this study is three-fold: (i) to present a general higher-order shell theory to analyze large deformations of thin or thick shell structures made of general compressible…
