The present study investigates buckling characteristics of cut-out borne stiffened hyperbolic paraboloid shell panel made of laminated composites using finite element analysis to evaluate the governing differential equations of global buckling of the structure. The finite element code is validated by solving benchmark problems from literature. Different parametric variations are studied to find the optimum panel buckling load. Laminations, boundary conditions, depth of stiffener and arrangement of stiffeners are found to influence the panel buckling load. Effect of different parameters like cut-out size, shell width to thickness ratio, degree of orthotropy and fiber orientation angle of the composite layers on buckling load are also studied. Parametric and comparative studies are conducted to analyze the buckling strength of composite hyperbolic paraboloid shell panel with cut-out.

“…The effects of cutout size, panel curvature and initial geometric imperfections on the overall response of compression loading were described. Udar and Datta 6 studied the dynamic instability of laminated composite doubly curved panels with centrally located circular cutout under non-uniform compressive in-plane harmonic edge loading. Lee and Kim 7 implemented a finite element program to numerically characterize the compressive response and damage evolution in laminated plates containing a cutout based on the concept of the ensemble-volume average for laminated composites and a micromechanical constitutive model.…”

In this paper, the buckling behavior of an advanced grid stiffened (AGS) composite cylindrical shell with a rectangular cutout is systematically investigated using the finite element method. The effects of reinforcement dimension of cutout on the non-linear response of the AGS composite cylindrical shell are described. The simulational results illustrate the complex non-linear response of a compression-loaded AGS composite cylindrical shell with an unreinforced cutout. In particular, a local buckling response occurs on the shell near the cutout which is caused by local skin deformations near the cutout. In general, reinforcement around a cutout in a compression-loaded AGS composite cylindrical shell can eliminate the local buckling response near the cutout and increase the global collapse load of the shell. However, simulational results illustrate that which reinforcement configurations can cause an unexpected increase in the magnitude of local deformations in the shell and cause a reduction in the global collapse load. A parameter study, including the orientation, thickness and size of cutout reinforcement in the AGS composite cylindrical shells, was conducted to improve the buckling response characteristics by determining a set of appropriate parameters.

“…They recognized three types of bending-torsion coupling caused by three different unbalances. Udar and Datta [9] considered a laminated curved panel having a circular hole under an external periodic force, and studied its instability characteristics under the primary and combination resonances. They showed that the instabilities caused by the combination resonances are as much important as the ones caused by the primary resonances.…”

In this paper, the combination resonance of a spinning composite shaft with geometric nonlinearity is studied by the method of harmonic balance. The full equations of motion containing the flexural-flexural-extensional-torsional coupling are employed for the analysis. The equations were discretized by both one and two modes, so two different forms of combination resonances can be analyzed. The shear deformation is neglected due to the shaft slenderness, whereas the rotary inertia and the gyroscopic effects are considered. The effects of different parameters such as external damping and the eccentricity on the response bifurcation of the shaft are investigated. The effect of the fiber orientation angle was also investigated. The results obtained for the composite shaft are compared to those of its metallic counterpart. It is shown that two geometrically identical shafts, one metallic and one composite, have different behaviors under the condition of combination resonance. It is observed that the vibration of the composite shaft occurs with smaller amplitude. This confirms the superiority of the composite shafts over metallic ones. Finally, the results were validated by the numerical simulations and there was a good agreement between the results.
