Mesh Considerations for Adaptive Finite Element Analyses of Cement Failure in Total Hip Replacement
INTRODUCTION Failure of the cement mantle has been identified as a possible mode of failure of the implanted femur in total hip replacement (THR) [1]. Finite element (FE) analyses have been used to investigate the stresses experienced in the cement mantle [2] and to predict the life of the cement mantle when taking different factors into account [3]. The number of elements used, or mesh density...
متن کاملFast 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 ...
متن کاملExperimental and Finite Element Analyses of the Hydrostatic Cyclic Expansion Extrusion (HCEE) Process with Back-Pressure
It is generally known that severe plastic deformation processes with back pressure not only apply higher hydrostatic stress and more deformation compared to what a regular process can apply to a workpiece but also prevent surface defects in the workpiece during the process. Hydrostatic cyclic expansion extrusion (HCEE) was developed recently for processing long ultrafine-grained metals and allo...
متن کاملFinite Element Analysis of Different Hip Implant Designs along with Femur under Static Loading Conditions
Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...
متن کاملMoving Particles Through a Finite Element Mesh
We present a new numerical technique for modeling the flow around multiple objects moving in a fluid. The method tracks the dynamic interaction between each particle and the fluid. The movements of the fluid and the object are directly coupled. A background mesh is designed to fit the geometry of the overall domain. The mesh is designed independently of the presence of the particles except in t...
