Web15 mrt. 2024 · Hyperelasticity Fracture Tearing energy Energy release rate Higher-order derivatives 1. Introduction In fracture mechanics, the energy fracture criterion has been used to determine the onset of growth of a pre-existing crack in a loaded body. WebThis expression introduces the definition of the equivalent plastic displacement, u ¯ p l, as the fracture work conjugate of the yield stress after the onset of damage (work per unit area of the crack).Before damage initiation u ¯ ˙ p l = 0; after damage initiation u ¯ ˙ p l = L ε …
