heterogeneous body

基本解释

Welded joint is a mechanical heterogeneous body, and the mechanical heterogeneity has great effect on dynamic fracture behaviour of welded joint.
焊接接头是一个宏观力学不均匀体，力学不均匀性对焊接接头的动态断裂行为有重要的影响。
The structure of rock is extremely complicated discontinuous and heterogeneous body, its mechanics property has non-linear, anisotropism and rheology characteristic, which changed over time.
岩石的结构是极其复杂的非连续和非均质体，其力学属性具有非线性、各向异性及随时间变化的流变特性。
It is a brittle material and heterogeneous discontinuous body. The process of its failure is one of initiation of inner cracks of the rock followed by their propagation, connection and link up.
它是一种非均质不连续体的脆性材料，其破坏过程是在水力或机械作用下，岩石内部裂纹的产生、扩展、合并和贯通的过程。
