Abstract
This paper describes recent developments at Northwestern University in the modeling of inelastic deformations of concrete due to progressive microcracking, as well as their use in fracture analysis. A review of the crack band theory is presented and the stress-strain relations for progressive microcracking are analyzed. For the purpose of general loading, the microplane model which is an analog of Taylor-Batdorf-Budianski's slip theory of plasticity, is described and its use in numerical structural analysis is discussed. It is also shown that the crack band theory along with a microplane model generalized for crack unloading is capable of describing the resistance of cracks in concrete to shear. Some comparisons with test data are demonstrated.
