Finite Element Method Simulation of Photoinductive Imaging for Cracks

In this paper, the numerical simulations of photoinductive imaging (PI) method have been performed using the finite element method (FEM) with the 2D transient to characterize corner cracks at the edge of a bolt hole. The PI imaging results have higher spatial resolution in the area of the defect in 2D models as compared with the conventional eddy current (EC) images. The FEM simulation results ...

Validation of Crack Interaction Limit Model for Parallel Edge Cracks Using Two-dimensional Finite Element Analysis

Shielding interaction effects of two parallel edge cracks in finite thickness plates subjected to remote tension load is analyzed using a developed finite element analysis program. In the present study, the crack interaction limit is evaluated based on the fitness of service (FFS) code, and focus is given to the weak crack interaction region as the crack interval exceeds the length of cracks (b...

Using Pattern Search Algorithm and Finite Element Method to Detect Rotor Cracks

The vibration pattern of a rotor system reflects the mechanical parameter changes in the system. Hence, the use of vibration monitoring is considered as a possible means of detecting the presence and growth of the cracks. In this paper, a pattern search based method for shaft crack detection is proposed and described which formulates the shaft crack detection as an optimization problem by means...

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...

A Finite Element Model for Simulating Flow around a Well with Helically Symmetric Perforations

In a perforated well, fluids enter the wellbore through array of perforation tunnels. These perforations are typically distributed in a helical pattern around the wellbore. Available numerical models to simulate production flow into cased-and-perforated vertical wells have complicated boundary conditions or suffer from high computational costs. This paper presents a simple and at the same time ...
