复合材料偏心加筋壳特性分析

Analysis of behaviors of composite laminated eccentrically stiffened shell

用任意加筋壳单元研究了复合材料偏心加筋壳结构的特性.研究表明,在结构几何尺寸已经确定的情况下,可以调整加强肋骨的偏心量,以改变加筋壳结构内部的受力和变形;调整加强肋骨的布置方式也是改变加筋壳结构强度和刚度的有效方法.

The behavior of a laminated composite eccentrically stiffened shell is studied with a new stiffened shell element. The results indicate that when the shape and size have been determined, the stress and strain of a stiffened shell structure can be adjusted by changing the eccentricity of the stiffeners ; the strength and stiffness of a stiffened shell structure can also be adjusted by changing the arrangement of the stiffeners.
