Fracture Mechanics of Concrete – State-of-the-Art Review ...

10%  Dec 31, 2010  The approach of fracture mechanics to study the nonlinear fracture behavior of concrete can be introduced analytically (or semi-analytically) and numerically. Under the first category, the nonlinear fracture models based on equivalent elastic crack length and using the principle of linear elastic fracture mechanics may be considered.

State-of-the-Art Review on Concrete Softening Curve ...

The cohesive crack model is widely employed to the fracture analysis of concrete for mode I crack. The tension softening relationship is a very important constitutive law in the cohesive crack model. The determination methods of tension softening relationship of concrete are introduced in this paper which are direct tension methods, J-integral method and inverse analysis method.
