Two and three dimensional finite element models (FEM) were developed to simulate the behavior of a fractured jaw bone and the fixation materials. Mini-plates with various geometric and material properties and screw combinations were considered. Their effects on the variation of maximum stress contours were investigated. The geometric and material properties of the plate, screw and bone were see...

In this study, ANSYS finite element software is used to simulate the temperature and stress field in the laser powder deposition process. The model is used to determine the effect of the deposition pattern on the final stress distribution. Four deposition patterns are defined to cover the same area: long bead, short bead, spiral in, and spiral out. The results show that the deposition pattern s...

The effect of joint size on the loading capacity of wood single lap joints was studied with an orthogonal experimental design. The maximum load, modulus of elasticity, and modulus of rupture were the three mechanical indexes used to evaluate wood joint quality. A simulation model of bending tests was established using the finite element method. The stress distributions of the joints were analyz...

The intralaminar screw construct has been recently introduced in C6-C7 fixation. The aim of the study is to compare the stability afforded by three different C7 posterior fixation techniques using a three-dimensional finite element model of a C6-C7 cervical spine motion segment. Finite element models representing three different cervical anchor types (C7 intralaminar screw, C7 lateral mass scre...

Abstact:The term “stressstrength reliability” when it appears in statistical literature typically refers to the quantityP(X > Y), where a system with random strength X is subjected to a random strength Y such that a system fails, if the stress exceeds the strength. Stress –Strength reliability is considered in this paper where the strength follows finite mixture of two parameter Lindley distrib...

A human vertebra was modelled using the finite element method (FEM), to investigate likely sites of failure under prescribed loading. The FEM stress analysis proved that the stress distributions in the second cervical vertebra (axis) are influenced by the direction of the applied load on the anterior surface of the odontoid process. The regions of high compressive stress could be found on the i...

in this study, a new method for joining aluminum tubes in subsurface structures using steel converting and aluminum welding are presented and reviewed. but near the weld area is under high thermal cycle and will cause residual stresses in heat affected zone. therefore for assessment of proposed connection from the perspective of residual stress by using the finite element method welding of tube...

A finite element model is used to explore the stress-strain responses of the mandibular central incisor and its associated periodontal ligament (PDL) while opening the bite. The finite element model consisted of the mandibular teeth, the alveolar bone, and the PDL of the mandibular incisors. The clinical scenario was simulated by applying a force of 10 cN to the mandibular incisor in a crown-ro...

Mathematical modeling, finite element numerical simulation and experimental measurement of the stress-deformation distribution gas-insulated metal-enclosed transmission line shell were carried out. Also, Stress linearization analysis was used to analyze maximum stress. The results show that stress is linearly dependent on water pressure occurs elastic deformation without plastic deformation. si...
