Stress concentration reduction using different functionally graded materials layer around the hole in an infinite panel

The present work aims to study the stress concentration factor (SCF) reduction using different functionally graded materials (FGMs) layer around the circular hole in an infinite homogeneous material panel for different load conditions. Young’s modulus of FGM layer has been considered to be varied along radial direction while Poisson’s ratio has been kept constant. The extended finite element method (XFEM) is used to find the effect of FGM layer properties i.e. Young’s modulus ratio, power law index and layer thickness on SCF. Four FGM models have been used in the present work out of which power law function based thicker FGM layer ensure the least value of SCF. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Strength, Fracture and Complexity IOS Press

Abstract

The present work aims to study the stress concentration factor (SCF) reduction using different functionally graded materials (FGMs) layer around the circular hole in an infinite homogeneous material panel for different load conditions. Young’s modulus of FGM layer has been considered to be varied along radial direction while Poisson’s ratio has been kept constant. The extended finite element method (XFEM) is used to find the effect of FGM layer properties i.e. Young’s modulus ratio, power law index and layer thickness on SCF. Four FGM models have been used in the present work out of which power law function based thicker FGM layer ensure the least value of SCF.
