Stress concentration beam with hole

WebSep 22, 2024 · Stress concentration caused by the open-hole is another concern in the design of composite beams. In the research conducted by Rezaeepazhand et al. , the emphasis was placed on the stress concentration around the open-holes of the composite beam webs subjected to uniaxial tension load. The obtained results validated the … WebFig.2.14 Stress intensity factor correction factor for a crack emanating from a hole. (a) Two symmetrical cracks emanating from a circular hole and (b) the stress intensity factor. Solution Due to the stress concentration near the circular hole (K t = 3) an element at the rim of the hole is subjected to a tensile stress 3 σ along the y-axis ...

WebThe smaller of the two computed stresses is to be used. For combined stresses, as discussed in Section 10.4, the shear design stress is used. The code also applies a factor of 0.75 to the calculated design stress if the section being considered includes a keyway. It is noted that this is equivalent to a stress concentration factor of 1.33.

WebCause: The stress concentration in a body happens because of the sudden change in the geometry of the body due to cracks, sharp corners, holes, decrease in the cross-section area.
