曲线坐标系下三维弹性壳体中的微分几何关系
Differential geometric relations on the three-dimensional elastic shell in the curvilinear ordinates systems
摘要
Abstract
The differential geometric relations between 3D elastic shell and the middle surface of shell are provided,which is of importance for forming 2D linear and nonlinear elastic shell mod-els.Concretely,the metric tensor,the determinant of metric matrix field and the Christoffel symbols on the 3D elasticity are expressed by those on the 2D middle surface,which are featured by the asymptotic expressions with respect to the variable in the direction of thickness of the shell.关键词
