THE THERMODYNAMIC FRAMEWORK OF THE NONLIN EAR FRACTURE-MECHANICS

Surprising results of measurements of the interfacial fracture toughne ss of the interface made from otherwise brittle materials is merely an other impetus for think over restrictions of the nonlinear fracture me chanics. With respect to the extensive energy dissipation Rie are of t he opinion that in the nonlinear fracture mechanics it is no longer po ssible to ignore the second law of thermodynamics. Its proper applicat ion can, in our opinion, quantitatively explain the behaviour of the c rack in different systems exposed to different conditions by virtue of the influence of dissipation processes.
