An Inversion Method of DDA with BEM

  • On the basis of BEM(boundary element method),DDA(discontinuous deformation analysis) and Least Square Principle,a method for determining relative movements on boundaries,displacements and stresses in blocks of a multi-block system is presented,the stress and kinematic constraints required for the movement reasonability of the block system are discussed,and the judgment of the contact status between blocks is also investigated in detail,that ensures whether stress and kinematic constraints are necessary.In one word,an inversion method of DDA with BEM is provided,that would be a more effective numeric computing method for larger-scale crustal deformation analysis.
