Post-buckling and First-ply Failure of Thin-walled Frames and Columns Made of Composite Materials
First-ply failure (FPF) of composite thin-walled columns and frames is investigated in the buckled structure. Elastic behavior is assumed during the pre-buckling and buckling states, and along part of the post-buckling equilibrium path. The Tsai-Hill criterion is employed to identify failure of one ply at one specific location. The technique of analysis is based on evaluation of the post-buckli...
متن کاملBuckling Analysis of Spherical Composite Panels Reinforced by Carbon Nanotube
In this study, the buckling behavior of moderately thick Carbon Nano-Tube (CNT)-reinforced spherical composite panels subjected to both uniaxial and biaxial loads is examined. The uniform and various kinds of functionally graded distributions of the CNT are considered. The mechanical properties of the nanocomposite panels are estimated using the modified rule of mixture. Based on the first-orde...
متن کاملBuckling and vibration analysis of angle -ply symmetric laminated composite plates with fully elastic boundaries
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully elastic boundaries. It has been observed that o...
متن کاملPly Level Uncertainty Effects on Failure of Composite Structures
Composite materials are popular in aerospace engineering because of their light weight, high strength to weight ratio, stiffness to weight ratio and tailoring properties. However, the modeling of composites is still a challenging task because of its highly uncertain material properties which arise from the manufacturing process.The effect of material uncertainties in failure strength and reliab...
متن کاملTheoretical and experimental predictions of first-ply failure of a laminated composite elevated floor plate
Experimental and theoretical approaches are studied via the first-ply failure strength on anti-symmetrically laminated composite elevated floor plates with various length-to-depth ratios, aspect ratios, and optimal fibre orientations subjected to central point loads. Optimal angle-ply orientations of anti-symmetric [θ/ − θ . . .]−S laminated composite plates designed for maximum stiffness were ...
