ANISOTROPIC PHASE-FIELD DESCRIPTION OF VON KÁRMÁN BEAMS
Original language description
For brittle materials with complex crack topology, discrete crack approach suffers from implementation complexity. The phase-field formulation can overcome this issue. In this paper, using phase-field approach for brittle beams and plates is reviewed. We assume that the damage appears only in tension, meanwhile in compression the material is intact. Accordingly, the damage field for these cases is only scalar field and each FEM node has only one extra unknown variable. Moreover in staggered approach, calculation is divided into two linear forms and inner iterative procedure is not needed for Mindlin beams. It does not hold for von Kármán large deflection formulation as presented at the end of the text.
