Stress intensity factor for hypocycloidal hole in finite plate

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

“…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].…”

“…M.M. Chauhan et al have determined the stresses and SIF around the polygonal and hypocycloidal hole during the anisotropic finite plate subjected to in-plane loading [1,63,64] .…”

The effects of composite laminate stiffness and loading on stress resultant concentration factor around a hole

“…Some of such works make use of numerical approaches such as finite element analysis (FEA) [1][2][3][4][5] whilst others focus on the use of fast and precise analytical methods. [6][7][8][9][10][11][12][13][14][15] Experimental techniques complement the two previous approaches and have been used extensively to validate both analytical and numerical solutions.…”

“…16 For example, Bonora et al 6,7 provided closed-form solutions for stress state around circular and elliptical holes in the laminated composite plates using the classic Airy solution method. Amongst similar works are the works of Chauhan et al 10 They employed an analytical complex variable method and studied the effect of stacking sequence on tangential stresses around a rectangular hole under uniaxial loading for a finite graphite/epoxy composite plate. For their laminate of study, they concluded that maximum and minimum SCF take place for [0 8 ] s and [90 8 ] s lay-up, respectively.…”

“…Excellent agreement was established between the proposed analytical method and experimental results. Although SCF around circular/elliptical holes represents the case in most engineering applications, some researchers investigated SCF around holes of various other shapes such as triangular, 18,19 rectangular, 11 hypocycloidal, 10 polygonal 17,20 and irregular 21,22 holes.…”
