The thickness of shell element is design variable.

本文问题的提法是假设薄板的厚度给定，壳单元的厚度为设计变量，给定约束和荷载的条件下，求加强筋在薄板上布置的几何形状，使薄板结构使用材料最省，满

Also being with the metamorphic crystalline basement formed later and suffered the stronger tectonic event and the material composition reforming, being composed of the material with low density and existing the relatively weak intrinsic mechanical system, Huaxia massif was affected by the various tectonic movement in the later period, the layers inside the lithosphere interacted under action of the tectonic force, this led to the material composition and the structure regulated and changed constantly by the magmatism in the crust, underplating and faulting and folding, therefore, the ability to resist the deformation decreased with the every variation.

华夏地块变质结晶基底形成时代晚，并遭受更多更强构造变动与物质组分的改造使之物质组成密度较小，岩石圈先期固有的力学结构系统相对较弱，尤其是后期的地球大系统的历次构造运动都对其施加影响，构造动力作用下引起内部圈层间相互发生作用，导致内部物质成分、结构形态通过壳内岩浆活动、地幔底侵作用、断裂褶皱等不断的调整重组重建而变化，其每一次调整变化，都使其总体抵抗变形能力进一步降低。

The elastoplastic dynamic behaviors of space lattice structures are thoroughly analyzed under multiple support excitation and simple support excitation.
