A cohesive finite element for quasi-continua

In this paper, a cohesive finite element method (FEM) is proposed for a quasi-continuum (QC), i.e. a continuum model that utilizes the information of underlying atomistic microstructures. Most cohesive laws used in conventional cohesive FEMs are based on either empirical or idealized constitutive models that do not accurately reflect the actual lattice structures. The cohesive quasi-continuum f...

Triangle Transducer for Micro Electro Mechanical Systems (MEMS) Simulation in ANSYS Finite Element Program

The paper introduces a new methodology with a distributed triangle transducer for the strongly coupled simulation of micro electro mechanical systems (MEMS) in ANSYS Finite Element (FE) program.

Finite Element Analysis of Micro – Electro – Mechanical Systems by using the ANSYS software

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...

Time continuity in cohesive finite element modeling

We introduce the notion of time continuity for the analysis of cohesive zone interface finite element models. We focus on “initially rigid” models in which an interface is inactive until the traction across it reaches a critical level. We argue that methods in this class are time discontinuous, unless special provision is made for the opposite. Time discontinuity leads to pitfalls in numerical ...
