A micro‐scale‐based approach for the numerical analysis of cement‐based materials, subjected to low‐ and high‐cycle fatigue actions, is presented in this paper. The constitutive model is aimed at describing the evolving microstructural changes caused by cyclic loading protocols. The plastic‐damage‐based model is formulated combining the concepts of fracture‐energy theories and damage stiffness degradations,...
This paper provides preliminary results of a research study on the fatigue behavior of Ultra‐High‐Performance Concrete (UHPC). Results of an experimental campaign, performed at the Department of Concrete Structures and Structural Engineering of the TU‐Kaiserslautern, are firstly proposed. The heterogeneous meso‐structure and material degradation of UHPC are studied through cyclic bending‐tensile tests...
