A Virtual Element Method for elastic and inelastic problems on polytope meshes [PDF]

open access: yesComputer Methods in Applied Mechanics and Engineering, 2015
We present a Virtual Element Method (VEM) for possibly nonlinear elastic and inelastic problems, mainly focusing on a small deformation regime. The numerical scheme is based on a low-order approximation of the displacement field, as well as a suitable ...

Adhesive Boundary Element Method Using Virtual Crack Closure Technique

open access: yesFrontiers in Mechanical Engineering, 2021
In this study, a new adhesive contact model is built upon a boundary element method (BEM) model developed by Pohrt and Popov (2015). The strain energy release rate (SERR) on the edge of the bonding interface is evaluated using Virtual Crack Closure ...

A priori error analysis of virtual element method for contact problem

open access: yesFixed Point Theory and Algorithms for Sciences and Engineering, 2022
As an extension of the finite element method, the virtual element method (VEM) can handle very general polygonal meshes, making it very suitable for non-matching meshes. In (Wriggers et al. in Comput. Mech.

Study of the enwrapping of the front profiles of the active elements of a three-screw compressor [PDF]

open access: yesMATEC Web of Conferences, 2022
The paper proposes a method for identifying the front profile of a worm-type active element, consisting of a three-screw compressor. The purpose of this identification is to study the frontal enwrapping between the profiles of the driver and the driven ...
