AB  - This paper presents a constitutive equation for the postpeak stress–displacement relation- ship of concrete in uniaxial compression. The relationship is modelled in relation to the process of postpeak energy dissipation increasing the postpeak displacement of the localized damage zone. The proposed equation includes three material parameters: compressive fracture energy, compres- sive strength, and critical postpeak displacement. The nondimensional form of the equation shows that a parameter determined from these three material parameters controls the shape of the postpeak stress–displacement curve. The predictions produced by the proposed equation are fit to uniaxial compression test results from concrete specimens with different slenderness…
