For their discrete characteristics in production process, before the needs be well met, there
will be numerous preprocessing data need to be described: information of product feature,
machining and technology information, production planning data, information of product material
etc.

Wear of pick in soft and hard interbedded formation
In the process of cutting rocks, picks bear high periodic compressive stress, shearing stress and impact load, and its temperature rises quickly due to friction and impact action, leading to softening of body material and accelerating failure of pick.

Structure diagrams of the dam after reinforcement
Finite Element Model and Boundary Conditions
According to material properties and dam partition, finite element analysis model is established; Following is the range of finite element model: X direction is taken as perpendicular to the dam axis, Z direction takes coordinates for elevation.
