Investigation on mode-I crack propagation in concrete using bond-based peridynamics with a new damage model

A new damage model is proposed in the bond-based peridynamics (BBPD) frame to quantitatively investigate mode-I crack propagation in concrete, which is established based on the pattern of bilinear softening curve commonly used in the discrete cohesive zone model (CZM). This new damage model can be obtained completely based on material properties, that is, once experimental bilinear softening curve, the uniaxial tensile strength, the elastic...
