208 積層複合材料の非拘束条件における静的有限要素解析(材料力学I)
詳細
In this paper cross elasticity effects for general laminated composite plates and shells are presented. The discrete governing equations under unconstrained conditions can not be solved because the stiffness matrix is singular. The modified equations is obtained from reducing the dynamic equilibrium equations under the constant velocity motion and the Rayleigh damping proportional to the mass matrix. The validity of computational method is confirmed by comparison of analytical results for the classical laminaton theory.
