Appropriate Loading Techniques in Finite Element Analysis of Underground Structures
Stability of underground structures is assessed by comparing rock strength with induced stresses resulted from ground stresses. Rock mass surrounding the opening may fail either by fracture or excessive deformation caused. Accurate calculation of induced stresses is therefore fundamental in the stability analysis of an opening. Although numerical methods, particularly finite element method, are...
متن کاملA New Finite Element Formulation for Buckling and Free Vibration Analysis of Timoshenko Beams on Variable Elastic Foundation
In this study, the buckling and free vibration of Timoshenko beams resting on variable elastic foundation analyzed by means of a new finite element formulation. The Winkler model has been applied for elastic foundation. A two-node element with four degrees of freedom is suggested for finite element formulation. Displacement and rotational fields are approximated by cubic and quadratic polynomia...
متن کاملStatic Analysis of Orthotropic Functionally Graded Material Cylinders with Finite Length by a Mesh-Free Method
In this paper static analysis of orthotropic functionally graded material (FGM) cylinders with finite length was carried out by a mesh-free method. MLS shape functions are used for approximation of displacement field in the weak form of equilibrium equation and essential boundary conditions are imposed by transformation method. In this simulation, an ax symmetric model is used. Mechanical prope...
متن کاملCover interpolation functions and h-enrichment in finite element method
This paper presents a method to improve the generation of meshes and the accuracy of numerical solutions of elasticity problems, in which two techniques of h-refinement and enrichment are used by interpolation cover functions. Initially, regions which possess desired accuracy are detected. Mesh improvment is done through h-refinement for the elements existing in those regions. Total error of th...
متن کاملProphylactic Vertebroplasty: A Parametric Finite Element Study
INTRODUCTION: There has been a dramatic rise in the use of vertebroplasty for the treatment of vertebral compression fractures over the last decade. There are estimated to be over 700,000 such fractures each year in the United States alone, many of which lead to severe pain and a significant reduction in quality of life [1]. In the short term, vertebroplasty has been shown to reduce the pain an...
