This article introduces simulations of theoretical material with controlled properties for the evaluation of the effect of key parameters, as volumetric fractions, elastic properties of each phase and transition zone on the effective dynamic elastic modulus. The accuracy level of classical homogenization models was checked regarding the prediction of dynamic elastic modulus. Numerical simulations were performed with the finite element method for evaluations of the natural frequencies and their correlation with through frequency equations.

- Strain-Hardening Cement-Based Composites (SHCCs) provide high toughness and durability but are not widely used due to challenges in developing effective analytical models for their optimization and design.
- The mechanical response of SHCCs is influenced by multiple factors, including fiber characteristics and matrix strength, making it complex to predict.
- This research reviews the mechanisms behind SHCC cracking and offers predictive techniques for its tensile behavior, highlighting research gaps for further investigation to enhance the use of SHCC in resilient structures.
