A semi-analytical constitutive model of a porous cracked rock is proposed based on the
micro–macro approach within a thermodynamic framework. The representative volume …

Fracture and Size Effect in Concrete and Other Quasibrittle Materials is the first in-depth text
on the application of fracture mechanics to the analysis of failure in concrete structures. The …

A simple but general model for normal/shear cracking in quasi-brittle materials is presented.
It is defined in terms of the normal and shear stresses on the average plane of the crack and …

The first part of this two-part study presents a new improved microplane constitutive model
for concrete, representing the fourth version in the line of microplane models developed at …

In the paper, the microplane material model for concrete based on the relaxed kinematic
constraint is presented. The model is aimed to be used for three-dimensional damage and …

A general three-dimensional micromechanical approach to modeling anisotropic damage of
brittle materials such as concrete, rocks, or certain ceramics is presented. Damage is …

The paper presents an improvement of the microplane model for concrete—a constitutive
model in which the nonlinear triaxial behavior is characterized by relations between the …

The microplane model is a versatile constitutive model in which the stress-strain relations
are defined in terms of vectors rather than tensors on planes of all possible orientations …

The paper deals with the microplane model, in which the stress-strain relations are defined
independently on planes of all possible orientations in the microstructure, and the …

The strength and ductility of reinforced concrete (RC) columns can be substantially
enhanced though lateral confinement which may be provided by transverse steel …
