Abstract

Dynamic crack propagation and arrest phenomena have been considered in this paper. Finite element simulation based on the REMESHING technique, has been used to analyze the mode I fracture problem in a DCB specimen. A plane stress condition is invoked in the present two dimensional analyses. Specimens have been made from an Araldite-B polymer which is a brittle material. Both fixed load and fixed displacement loading conditions have been used to investigate their effects on the fast fracture. A dynamic fracture toughness criterion has been employed to find the crack propagation velocity and crack tip location at each time step. According to the new crack tip position, a REMESHING technique has been used. based upon this new position and then nodal data is transferred from the old mesh to the new mesh according to the elements shape function. The AXSYS 7.0 standard finite element code and related APDL programming facilities have been employed for modeling the problem. Comparison of the predicted results with those cited in the literature has shown good agreement.
