On the buckling behavior of cross-ply laminated composite plates due to circular/elliptical cutouts

Buckling analysis of laminated composite plates with an elliptical/circular cutout using FEM

“…Experiments showed fine agreement with the finite element results in the buckling load and the postbuckling strength. Ghannadpour et al [9] studied the influences of a cutout on the buckling performance of rectangular plates made of polymer matrix composites (PMC). The study was concentrated on the behavior of rectangular symmetric cross-ply laminates.…”

Acoustic Emission based Monitoring of Cut-out Geometry Effects in Carbon-Epoxy Laminates under Uni-axial Compression

“…They also stated that angle ply composite laminates with cutouts are less effective to stress concentration. Ghannadpour et al [5] addressed the size, shape and the plate aspect ratio of the circular cut-outs in affecting the compression behaviour of the laminates. They find that the plate with cut-outs requires high load than corresponding plate without cut-outs.…”

Analysis on the Effects of Cut-Outs in Hollow Inconel 718 Gas Turbine Shafts

“…The stress distribution around the cutouts and Open Journal of Applied Sciences along the shaft gives a clear idea of the geometry and orientation of cutouts for reduction of vibration in gas turbines [3]. Ghannadpour et al [4] have demonstrated in their study that buckling strength of rectangular laminated composites reduces with increase in hole diameter. Also for elliptical cut-outs it is observed that buckling strength increases when loaded in the direction along their major axis.…”
