Stress concentration at the corners of polygonal hole in finite plate

Effect of various discontinuities present in a plate on stress concentration: a review

“…The maximum stress concentration is determined for [90 8 ]s whereas the minimum is determined for [0 8 ]s and [0 4 /±45]s for a rectangular hole. The results obtained by that technique were compared with the literature and were given the similarity in results [1,63,64]. Vishal Mehta et al was used the complex variable method and least square method to find the stresses in a finite composite plate containing multiple holes subjected to uniaxial loading.…”

“…The highest normalized value of SIF for uniaxial Y loading was at 0°cusp of 3 and 5 cusp hole while it was at 0°and 180°cusp of 4 cusp hole. Under uniaxial X loading, the highest SIF value was observed at 72°and 288°cusp of 5 cusp hole, at 90°and 270°cusp of 4 cusp hole and at 120°and 240°cusp of 3 cusp hole [1,63,64].…”

Analytical Thermal Stress Analysis of Perforated Symmetric Composite Laminates Containing a Quasi-Triangular Hole

“…Tarn and Wang [7] obtained stresses due to thermal loads in an anisotropic elastic plate with a circular hole by applying the Lekhnitskii complex variable technique and by assuming the plane strain and plane stress conditions. Sharma and Chauhan [8] studied stresses induced surrounding a noncircular hole in an anisotropic finite laminate subjected to mechanical loading using the complex variable technique. The parameters such as the plate size and the hole geometry were investigated.…”

Hot spot along corner curvature of rectangular plate opening

“…Location of maximum stress is found to be in a wide range considering lamina arrangements. Paper [3] performed the similar analysis at the corners of polygonal hole of the finite plate. Finite element method and conformal method are used to obtain stress field around an opening in [4].…”
