Hadi eskandari

Volume 11, Issue 1 , January 2022

https://doi.org/10.22050/ijogst.2022.244926.1560

Abstract
  This work pertains to investigate the values of the stress intensity factor (SIF) in a functionally graded spherical pressure vessel with an embedded surface defect (semi elliptical crack) under thermo-mechanical loading. The three dimensional finite element analysis is performed to evaluate the SIFs ...  Read More
