FEM DYNAMIC FRACTURE ANALYSIS OF CONCRETE BEAMS

This is a description of additional numerical modeling of the dynamic fracture of impacted concrete and mortar beams using the fracture process zone approach. The input data for the finite element analysis consisted of the static material properties, including the tensile and compressive strengths, modulus of elasticity, Poissson's ratio, and density. The static and dynamic work of fracture was also used in this modeling. The good agreement between computed and measured slopes for the crack extension histories and strain histories is considered a validation of previous work on nonlinear model for the fracture process zone in impacted concrete and mortar beams. The three critical crack opening displacements of the constitutive relation are strain rate-invariant for the strain rate regime studied. These and other findings are discussed.
