20.500.12556/RUL-116662 Multiple wrinkling mode transitions in axially compressed cylindrical shell-substrate in dynamics We propose an efficient computational model for predicting the surface wrinkling in axially compressed bi-layer cylindrical shell-substrate composites. To capture the transitions between the wrinkling modes in the far post-buckling regime, we use implicit dynamics. In this context we apply a generalized and an energy-decaying time stepping schemes that numerically dissipate in the high frequency range. The other components of the model are a geometrically exact, rotation-less, nonlinear shell finite element for the cylinder and an elastic foundation that represents the substrate. We show that the proposed computational model predicts the wrinkling pattern transition from axisymmetric to diamond-like mode, which is consistent with the numerical and laboratory experiments reported earlier. Furthermore, the results of our computational model show the existence of several diamond-like mode jumps in the post-buckling regime, a result that has not yet been reported for the axially compressed shell-substrate cylinders. civil engineering thin-walled structures shell-substrate cylindrical composite axial compression wrinkling pattern transition mode jumping dissipative implicit dynamics schemes gradbeništvo gradbene konstrukcije cilindrični kompozit iz lupine in substrata osni tlak preskok oblike true true true Angleški jezik Slovenski jezik Članek v reviji 2020-06-01 14:09:39 2020-06-01 14:24:10 2023-04-19 16:00:08 0000-00-00 00:00:00 2020 0 0 Str. 1-12 št. 1, 106700 Letn. 150 maj 2020 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624.07 0263-8231 10.1016/j.tws.2020.106700 9108321 26529536 bbrank@fgg.uni-lj.si-Cilindri-R1-TWS-Final-WTC.pdf bbrank@fgg.uni-lj.si-Cilindri-R1-TWS-Final-WTC.pdf 1 5D5A2C267055B4DF2B89B0E052CE9DEE 674129ae028f214e23aecf13788f7c5027fa425ca22aef7390fe52307b6a0f54 fba0de0c-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130313 https://doi.org/10.1016/j.tws.2020.106700 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=130315 Fakulteta za gradbeništvo in geodezijo 0 0 0
