Furthermore, most FEM (finite element method) codes for adaptive analyses are based on triangular and tetrahedral elements, due to the simple fact that triangular and tetrahedral meshes can be automatically generated. However, these elements possess significant shortcomings, such as poor accuracy in ...
On this basis, numerical simulation of a single-pick cutting seafloor massive sulfide based on the FEM-SPH adaptive coupling algorithm is carried out. Through the research in this paper, the regularity of the fragmentation process of polymetallic sulfides is obtained: firstly, the br...
Systems and methods of computational technical analysis using a hybrid approach of finite element method (FEM) and adaptive smoothed particle hydrodynamics (SPH) are described. In one aspect, a computer aided engineering analysis is performed to simulate an impact event between structures. An FEM ...
