Hello, any simulation process, that deals with the insertion of a secondary material introducing into a master material, may be of help.
For example, a first 0.2 cubic meter gravel is added into a hole in the ground to get compacted, next, another 0.2 cubic meter is added in, and get compacted again. Then we can investigate the compaction effect in the soil below the compacted gravel.
Similar models may be used in civil engineering (such as Franki piling) and manufacturing engineering (such as metal powder compaction).
My concern is that how we can model the above process? I would like to listen to your ideas. Regards. David
