WebCrack propagation may be described using the energy criterion theory ( Griffith, 1920) which is based on thermodynamic and energy balance. The theory predicts that a crack will propagate in order to lower the total energy of the system, by dissipating the elastic strain energy due to loading into the creation of a new surface. WebJul 31, 2024 · The Griffith-lines for elastic or environmentally assisted or elastic–plastic crack growth is shown in the figure along with the superimposed behavior of smooth specimens. One can, in principle, define the internal stress triangle that quantifies the additional in situ generated minimum stresses and their gradients required to ensure …

WebBy means of nonlocal elasticity theory, the Griffith crack problem is solved to determine the state of stress in a plate weakened by a line crack. The maximum stress is found to be finite and occurs away from the crack tip. Cohesive stress is estimated and compared with the calculations based on atomic lattice theory.
