Stress concentration beam with hole
Web2.3 Stress Concentration Factors for Notched CLT Beams For notched CLT beams also stress concentration factors were determined by means of the FE-model described in section 2.1 using the same assumptions as for CLT beams with holes, i.e. the width of lamellae was set to 150 mm and ratios of tnet,cross/tgross = 0.20 and tgross/nCA = 50 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 …

WebThe stress at the edge of a hole, or at a notch root, has a higher value than the remote stress. This phenomenon is called ‘ stress concentration ’. Fatigue cracks mostly initiate at the sites of stress concentrations. Once a crack initiates, we have to consider the stress concentration of the crack. However, it must be noted that the ... http://www.ucmengineering.weebly.com/uploads/2/6/2/8/26280571/engr_151-lab_6.pdf
