SEMI-ANALYTICAL ELEMENT METHOD FOR CONCRETE CRACK PROPAGATION BASED ON BILINEAR COHESIVE FORCE MODEL
The stiffness matrices and external force vectors of ring and circular singular hyper-analyticalelement are formulated by substituting basic analytical solutions into variational equation in Hamiltonian form. The assemblage of the two hyper-analytical-elements leads to a precise description of the displacement and stress fields in the vicinity of crack tip for a cracked plane acted a bilinear cohesive force on the crack surfaces. Numerical results of benchmarks show the efficiency and accuracy of the method.
