In this paper, the crack growth and variations of stress intensity factor in rotary disks with central hole is studied. For modeling and analyzing samples, the FRANC2D software is used and to predict stress intensity factor, DACE emulator (Design & Analysis of Computer Experiments) is used and, at the end comparison between results of modeling and results of simulator has been done. The emulato...

An extension of the contour integral method (CIM) for the computation of stress intensity factors for loaded cracks is presented. Numerical solutions of the two-dimensional linear elasticity equations are computed with the p-version of the generalized finite element method. Polynomial enrichment functions as well as enrichment with near crack tip asymptotic expansion are used. The robustness of...

Now a days product development using prototype methods for actual usage is a growing concept in engineering. Present work deals with simulation of Compact Tension specimen to get fracture parameters J – integral and Stress intensity factors of product built by polyjet technology 3D printer additive manufacturing system. FEA simulation is carried out with the help of Abaqus software by simulatin...

This article focused on the stress analysis of an edge crack in a thin hallow rotating functionally graded material (FGM) disk. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. A comprehensive study is carried out for various combinations of the crack length and orientation with the different gradation of materials. The effect of non-unifor...
