Variational inequality‐based particle discontinuous deformation analysis
International journal for numerical and analytical methods in geomechanics (Print), 2019Orienting the circular and rigid particle medium, the variational inequality‐based discontinuous deformation analysis (DDA) is established. In the proposed DDA, the global stiffness matrix, the penalty parameters, and the open‐close iteration are ...

Discontinuous Deformation Analysis with Potential Contact Forces
International Journal of Geomechanics, 2019In conventional discontinuous deformation analysis (DDA), the procedure called open–close iteration is adopted to enforce the contact condition, which needs to repeatedly fix and remove the...
