Embodiment Construction
[0010] The working process of the inventive method is as Figure 1-Figure 4 shown.
[0011] figure 1 Flowchart of the implementation of the generic simulation box modeling and simulation method for 3D discrete element models.
[0012] Step 10 Input the geometric parameters of the three-dimensional simulation box to establish the outer contour of the simulation box, including the outer boundary plate and the inner boundary pressure plate. Both plates are composed of spherical particles with a particle size similar to that of the sample, and the boundary plate is rigid. , to apply boundary displacement, and the pressure plate is flexible to buffer boundary displacement and generate pressure.
[0013] Step 11 creates a close-packed body. Close-packed heaps are created by gravity deposition and cyclic compaction.
[0014] Step 12 assigns geometric conditions. According to the geometric shape and layered boundary conditions of the structure, the external coordinate file is rea...
