Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Study on Instantaneous Stiffness of CylindricalGear In Multitooth Meshes
Jixie chuandong, 1994 通过本文提出的分析轮齿刚度和齿面接触线载荷分布的新方法——台面接触线法向刚阵法，建立了齿面接触线上节点力与法向变形的关系。加入相应的变形协调条件和静力平衡条件，精确简便地作了多对齿同时啮合状态下，轮齿瞬时啮合刚度的分析计算。并用有限元方法编制了专用软件，文中给出了分析计算实例，获得了多齿对同时耦合时的啮合刚度曲线。计算结果具有较高的精度和可靠度。

Applied SciencesTime-varying mesh stiffness (TVMS) of the internal mesh transmission is a significant source of excitation that causes vibration and noise in planetary gear systems, and is also an important parameter in dynamics analysis. Currently, the calculation of mesh stiffness for internal gear pairs primarily relies on finite element simulation, and there still
