报告摘要:

The theory of elastic shells is one of the most important branches of the theory of elasticity. Among all the shell models, a classical and widely recognized model is the Koiter model. In this talk, we discuss the time-dependent Koiter model, which has not been addressed numerically. We show that the solution of the model exists and is unique. We provide the numerical scheme for the model. The corresponding analyses of existence, uniqueness, stability, convergence and a priori error estimate are given. Several numerical experiments with several kinds of shells, including the applications to the fields of biomedical and civil engineering, demonstrate the efficiency of the model.
