WebApr 11, 2024 · It shows that the tangential compressive stress σ θ is 5.8 times of the radial compressive stress σ r along the designed excavation boundary, and thus high compressive stress concentration occurs along the center-to-center line of perimeter holes. It is well known that in-situ stress performs a role in reducing blast-induced tensile stress ... WebThe results show that, when the modulus factor of elasticity increases, the stress …
Stress Concentration - Definition, Causes, Remedies
WebMar 17, 2008 · Elastic stress concentration factors (SCFs) for internally pressurized thick cylindrical vessels with oblique circular crossholes are reported. Results of finite-element analyses for two wall ratios (k equal to 2.25 and 4.5) and a range of crosshole ratios (d from 0.1 to 0.5) show that SCFs sharply increase with the inclination α of the crosshole axis. … WebStress Concentration Near an Elliptical Hole • In 1913 Charles Inglis (a British mathematician) published a solution for the elastic stresses near an elliptical hole in an isotropic infinitely large thin plate (the Inglis solution is discussed in Sec 4.2) • In this case the stress concentration depends on both the aspect ratio of origin of name zauhar
