COMPARISON OF COMPUTER PROGRAM FOR NONLINEAR DYNAMIC ANALYSIS OF THIN SHELL STRUCTURES

Three computer programs for nonlinear dynamic analysis, ADINA, STAGS and ILDYN, are compared with regard to accuracy of results and computer utilization. However, only two test cases are studied. The results presented in this report must consequently be handled with care. The main parameters of the test cases are: Thin shell structures, Linear elastic material, Non-linear geometric behaviour, Dynamic analysis, Stepwise linear load function, Unconservative pressure load. The analyses are compared to described test case and experimental measurements and show that nonlinear dynamic analyses may be very sensitive to the formulation of the problem.
