SHCC (Strain-Hardening Cement-Based Composites) be- long to the class of high-performance fibre-reinforced cement composites and are characterized by high post-cracking strength, deformability, and durability. The enhanced durability of structural elements significantly reduces the need for maintenance and rehabilitation measures, thereby substantially lowering material consumption and associated CO2 emissions over the entire life cycle. SHCC are also referred to as highly ductile fibre-reinforced concretes and are currently used primarily in structural engineering, seismic applications, repair and rehabilitation, and the production of precast elements. The tensile stress–strain relationship is an essential property for the characterization of these materials. To avoid complex and time-consuming direct tensile tests, a simplified inverse method for determining tensile properties based on flexural test results is presented. Digital image correlation (DIC) is employed as an efficient tool for material characterization.
