The process of filling materials is related to studies of soil and medium mechanics.
The filling performance for different materials of the bucket after optimization For the mechanical excavator, the flow patterns inside the bucket of the different materials are different.
A DEM simulation model of bucket digging materials is established, and the mining process of the bucket for different materials is simulated and analyzed.
This study not only visualizes the process of digging materials but also provides a feasible way to design the bucket structure for different materials.

The materials have much higher strength such as fast construction, high load bearing capacity, high construction quality but those have a fatal weakness as well.
The engineering method not only adopts a science but also an engineering experience.
The first one requires detailed information on the materials and processes such as mechanical, thermal databased at high temperatue of each structural steels and derivation of load-bearing capacity as the temperature within a fire compartmentation is going up.
