Stress concentration at holes

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 …

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 https://tambortiz.com

WebThe torsion loading produces a maximum shear stress at the shaft surface calculated from f s = T r J (10-1) where the torque transmitted through the section is determined from the horsepower relation: T = h p ( 63, 000) n (10-2) The development of these relations can be found in standard texts. WebNov 4, 2024 · From the results of the tensile and bending tests, it is observed that the stress concentration at the edge of the stop-hole is reduced near the stress concentration at the circular hole by closing both crack surfaces between the stop-holes under the condition of the closed crack surface.

In solid mechanics, a stress concentration (also called a stress raiser or a stress riser) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such …
