Buckling of Cracked Laminated Composite Cylindrical Shells Subjected to Combined Loading

06.11.2012 | Hamidreza Allahbakhsh, Mahmoud Shariati, Applied Composite Materials, 2012

A series of finite element analysis on the cracked composite cylindrical shells under combined loading is carried out to study the effect of loading condition, crack size and orientation on the buckling behavior of laminated composite cylindrical shells. The interaction buckling curves of cracked ...

Effect of Manufacturing Method and Aging Environment on Painted Automotive Carbon Fibre Composite Surfaces

06.11.2012 | M. L. de Souza, J. I. Mardel, B. L. Fox, Applied Composite Materials, 2012

In this paper, the effect of various aging environments on the painted surface finish of unidirectional carbon fibre composite laminates, manufactured by autoclave and a novel out-of-autoclave technique was investigated. Laminates were exposed to water immersion, 95 % relative humidity and cyclic ...

Spatial Wavelet Approach to Local Matrix Crack Detection in Composite Beams with Ply Level Material Uncertainty

20.10.2012 | G. Sarangapani, Ranjan Ganguli, C. R. L. Murthy, Applied Composite Materials, 2012

Wavelet coefficients based on spatial wavelets are used as damage indicators to identify the damage location as well as the size of the damage in a laminated composite beam with localized matrix cracks. A finite element model of the composite beam is used in conjunction with a matrix crack based ...

Study on the Effect of Cure Cycle on the Process Induced Deformation of Cap Shaped Stiffened Composite Panels

16.10.2012 | Yong Miao, Jian-chuan Li, Zhi-hong Gong, Juan Xu, Kai He, Jian Peng, Yi-hua Cui, Applied Composite Materials, 2012

Cap-shaped stiffened composite panels offer many excellent properties such as low density, high strength, high stiffness to weight ratio, and design flexibility. During their manufacturing processes, however, thermo-curing inherently produces the undesired residual stresses and cure deformations, ...
