Dynamic Stability of Laminated Composite Curved Panels with Cutouts

Parametric combination resonance instability characteristics of laminated composite curved panels with circular cutout subjected to non-uniform loading with damping

“…Sivasubramonian et al [22] investigated the free vibration characteristics of curved panels with symmetrical square cutouts using finite element method. Sahu and Datta [23,24] investigated the principle instability regions for isotropic and laminated composite doubly curved panels with rectangular cutouts subjected to periodic compressive loading using Bolotin's method.…”

Dynamic Response Of Laminated Composite Shells Subjected To Impulsive Loads

“…However, studies on the response of laminated composite shells subjected to impulsive loads are limited. S. K. Sahu and P. K. Datta [1] investigated the dynamic stability of laminated composite curved panels with cutouts subjected to in-plane static and periodic compressive loads using the finite element method. The effects of size of cutout, ply orientation, static and dynamic load factors, curvature, geometry, and various boundary conditions on the instability behaviour of laminated composite curved panels with cutouts were carried out.…”

Dynamical stability and parametrical vibrations of the laminated plates with complex shape

“…From presented review it follows that buckling problems with non-uniform pre-buckle stress state are of special interest. There are few works in which vibration, buckling and parametric instability behavior of a laminated plate with internal cutouts were studied [10,12]ets. It should be noted that the finite element method (FEM) remains the only way for dealing with complex structures and the most versatile.…”
