Sažetak
This chapter explores the role of material heterogeneity in the study of the mechanical behavior of concrete. It presents the meso‐scale model, which is capable of providing different failure mechanisms leading to macro‐scale representation in terms of multi‐surface models for concrete, combining Drucker‐Prager for compression stress and Rankine for tensile stress. The chapter provides the meso‐scale model, with the cohesive links in terms of Timoshenko beam elements and a brief description of the model. It then presents the corresponding macro‐scale failure surface obtained with meso‐ scale model computations. The failure criterion is different under the force of tension or compression. Under tension, softening is activated simultaneously for all modes as soon as one failure surface becomes active, whereas under compression, the failure modes are handled separately. The compression force influences the shear strength threshold in a Mohr‐Coulomb manner.
