Description of an atomistic model of environmentally assisted fracture in terms of catastrophe theory

A simple atomistic model of environmentally assisted fracture exhibits behavior, in terms of crack extension and healing, which can be described using the formalism of catastrophe theory. More complex fracture models may also be amenable to such description. Work by Markworth and Hirth is cited. Lat...

Beschreibung
Zusammenfassung:	A simple atomistic model of environmentally assisted fracture exhibits behavior, in terms of crack extension and healing, which can be described using the formalism of catastrophe theory. More complex fracture models may also be amenable to such description. Work by Markworth and Hirth is cited. Lattice-strain effects, lattice-decohesion effects and lattice-strengthening effects are discussed.--C.M.L.S.
