The raw materials for AC preparation are mainly divided into wood and coal materials.
Wood raw materials are mainly composed of husk, crop straw and other biomass, while the coal raw materials are mainly composed of lignite, anthracite and pitch coke [4-7].

Discrete element method (DEM) is a powerful tool for the study of granular materials.
Numerical method is a complementary method, especially good for microscale analysis of granular materials.
Granular materials are composed of distinct particles which displace independently from one another and interact only at contact points.
The DEM can capture both the macroscale response and the microscale behavior of the granular materials.

By using suitable combinations of materials it is possible to improve the functional performance as well as the safety of car bodies and to reduce the consumption of raw materials at the same time.
The clinching technology can be used to join dissimilar good formable materials but the quality and strength of the joint generally decreases for materials with higher tensile strength.

Nowdays, the traditional elasticity method used to evaluate the seismic safety of high arch dams is unable to reflect the dynamic performance of concrete materials and nonlinear response under earthquake load, such as the generation and development of micro cracks, the damage development in dams and the rate-dependent behavior of dam concrete.
Damage Plasticity Model Dam concrete is a damage sensitive material.
Under external load, there is the generation and development of micro cracks in concrete material, and this will apparently decrease the strength and elastic modulus of concrete, the material characteristics is called damage softening effect.
