Fractional calculus derivation of a rate-dependent PPR-based cohesive fracture model: theory, implementation, and numeri...
Published in International Journal of Fracture
Rate-dependent fracture has been extensively studied using cohesive zone models (CZMs). Some of them use classical viscoelastic material models based on springs and dashpots. However, such viscoelastic models, characterized by relaxation functions with exponential decay, are inadequate to simulate fracture for a wide range of loading rates. To impr...
