Finite element model of laminate construction element with multi-phase microstructure

Finite Element Model Construction

Abstract This chapter explains the methodology to simulate total hip arthroplasty. Three-dimensional (3D) model of a femur was created from the Visible Human Project computed tomography dataset. Four different models of cementless hip stem were constructed from various file formats. Triangular surface mesh was manually repaired to ensure good finite element model for analyses. The implant surfa...

Nonconforming finite element approximation of crystalline microstructure

We consider a class of nonconforming nite element approximations of a simply laminated microstructure which minimizes the nonconvex variational problem for the deformation of martensitic crystals which can undergo either an orthorhombic to monoclinic (double well) or a cubic to tetragonal (triple well) transformation. We rst establish a series of error bounds in terms of elastic energies for th...

Multi - Level Finite Element

Fast Finite Element Method Using Multi-Step Mesh Process

This paper introduces a new method for accelerating current sluggish FEM and improving memory demand in FEM problems with high node resolution or bulky structures. Like most of the numerical methods, FEM results to a matrix equation which normally has huge dimension. Breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. For implementing ...

Finite element simulation of microstructure evolution during friction stir welding of automotive aluminum parts

7000 series Aluminum alloys are widely used in the automotive industries for structural lightweight components due to their exceptional high strength to weight ratio. However, this class of aluminum alloy is difficult to join by conventional fusion welding techniques so Friction stir welding (FSW) widely is used for welding this alloys. The process has been demonstrated to be effective and is c...
