Effects of Periodic Loading on Longitudinal Fracture in Viscoelastic Functionally Graded Beam Structures [PDF]
Journal of Applied and Computational Mechanics, 2022 This paper analyzes the effects of periodic external loading on the longitudinal fracture of a beam structure made of linear viscoelastic material. A longitudinal crack splits the cracked part of the beam into left-hand and right-hand crack arms.

Numerical verification of energy release rate and J-Integral in large strain formulation
Forces in Mechanics, 2023 The fracture criterion is a critical topic in fracture mechanics. However, the equality of J-Integral (J) and energy release rate (G) has not been numerically verified under large strain theory.

On Damage Strain Energy Release Rate Y [PDF]
International Journal of Damage Mechanics, 1995 In the application of the theory of damage mechanics to solve a wide range of practical engineering problems, a generalized formulation of damage strain energy release rate Y is required. This is because the damage strain energy release rate Y, which is the thermodynamic conjugate force of damage variable D, is used to derive damage evolution equation.
