Cracking and Fracture of Concrete at Meso-level using Zero-thickness Interface Elements
Abstract Since the pioneering numerical concrete of Roelfstra et al. (1985), mesomechanical analysis has been emerging as a powerful approach to predict the complex behavior of heterogeneous materials starting from relatively simple assumptions on the behavior of the constituents. The price to pay, however, is high computational cost associated to modeling explicitly the first-level heterogeneities of the material, in the case of concrete normally the larger aggregate pieces floating in a mortar matrix. Since that first attempt, a certain number of such models have been already proposed, first in 2D, more recently in 3D, some based on particle representations of the “DEM”-type or associated truss or beam structures between particle centers (Vonk 1992; Cusatis et al. 2003a,2003b, 2006; Bolander and Saito 1998; Bolander et al. 2000), some based on the regular lattice concept (Schlangen and van Mier 1993;Lilliu and van Mier 2003), and some on the classical continuum-type (Stankowski 1990; Wang and Huet 1993).
