Size-Dependence of Dynamic Behaviors for RCC Under High-Strain-Rate Loadings
The dynamic compressive strength usually is sensitive to both strain rate and specimen size, and larger specimens display a much more significant strain-rate effect. However, the size effect law for concrete-like materials is not fully understood under impact loading, resulting in an urgent need to extend size effect law to the full range of strain rates, applicable to both static and dynamic loadings. This study emphasizes the size effect on the dynamic compressive strength of concrete and on the damage/fracture process in general. Then, the exposed size effect on the dynamic mechanical properties is further analyzed and discussed to gain a deeper understanding of the physical mechanisms, and a strain-rate-dependent size effect law is developed to model the dynamic behavior of geometrically similar specimens.
