Experimental And Numerical Analyses Of A Thin Cylindrical Shell Model

The analysis of thin shell structures is generally based on theoretical principles. The experimental tests on this type of structure are important for understanding the effect of loading and the geometrical shapes on its mechanical behavior. In this paper, an experimental test of a cylindrical shell under the effect of concentrated static loads is presented. A comparative numerical study is carried out by using two finite elements: the first element called ACM_RSBE5, recently formulated, and the second one, S4R, of ABAQUS code are used for the study of thin shells. The experimental results are compared with those obtained numerically. The results of both elements, ACM-RSBE5 and S4R, are in agreement with those obtained experimentally. The efficiency and the importance of the approach of the flat shell element for thin shell structures are confirmed.
