Buckling and post-buckling behavior of various dented cylindrical shells using CFRP strips subjected to uniform external pressure: Comparison of theoretical and experimental data
Abstract Thin-walled circular cylindrical shells are used in many civil engineering applications. Any initial geometric imperfections and the type of applied load determine the buckling and the post buckling of cylindrical thin-walled shell structures. Fourteen thin-walled cylindrical shell models in two groups (labelled without CFRP and with CFRP) with different dent directions (H= horizontal, V= vertical and D= 45° diagonal direction) and dent depths (2tc and 4tc) subjected to external pressure were tested in the present research (tc is the thickness of the cylindrical shell). The results of testing under different theories and codes are compared. Moreover, the results are identified and investigated in the present experimental research.
Highlights Innovative experimental setup for thin walled shell structures. Wholly coverage of CFRP for thin walled cylindrical shells is not affordable. The experimentally observed initial, overall, and collapse buckling loads should be theories values multiply in some coefficients. The buckling failure occurred as a rise in the edges, and V-shaped collapse lines during the post-buckling stage.
