@article{(Open Science Index):https://publications.waset.org/pdf/3372, title = {A New Perturbation Technique in Numerical Study on Buckling of Composite Shells under Axial Compression}, author = {Zia R. Tahir and P. Mandal}, country = {}, institution = {}, abstract = {A numerical study is presented on buckling and post buckling behaviour of laminated carbon fiber reinforced plastic (CFRP) thin-walled cylindrical shells under axial compression using asymmetric meshing technique (AMT). Asymmetric meshing technique is a perturbation technique to introduce disturbance without changing geometry, boundary conditions or loading conditions. Asymmetric meshing affects predicted buckling load, buckling mode shape and post-buckling behaviour. Linear (eigenvalue) and nonlinear (Riks) analyses have been performed to study the effect of asymmetric meshing in the form of a patch on buckling behaviour. The reduction in the buckling load using Asymmetric meshing technique was observed to be about 15%. An isolated dimple formed near the bifurcation point and the size of which increased to reach a stable state in the post-buckling region. The load-displacement curve behaviour applying asymmetric meshing is quite similar to the curve obtained using initial geometric imperfection in the shell model.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {6}, number = {10}, year = {2012}, pages = {2040 - 2049}, ee = {https://publications.waset.org/pdf/3372}, url = {https://publications.waset.org/vol/70}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 70, 2012}, }
