Stress intensity factors and crack propagation path under mixed mode conditions [PDF]
Journal of Structural and Construction Engineering, 2016 Use of crack propagation principles based on SIFs (stress intensity factors) is among the most common methods of fracture mechanic engineering. SIF is an important parameter in fracture analysis. In analyzing elastic fracture, SIF reveals the stress near

Peridynamics for Fracture Analysis of Reflective Cracks in Semi-Rigid Base Asphalt Pavement
Applied Sciences, 2022 Reflective cracking is one of the major forms of deterioration in semi-rigid base asphalt pavements. It is, therefore, very important to have a correct understanding of the internal crack propagation mechanism of asphalt pavement to propose the most ...

Crack propagation in viscoelastic solids [PDF]
Physical Review E, 2005 We study crack propagation in a viscoelastic solid. Using simple arguments, we derive equations for the velocity dependence of the crack-tip radius, a (v) , and for the energy per unit area to propagate the crack, G (v) . For a viscoelastic modulus E (omega) which increases as omega(1-s) (0< s< 1) in the transition region between the rubbery region and
