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 ...
