Abstract

This paper presents results of deliberate tailoring of Engineered Cementitious Composites for impact resistance. Microstructure control involving fiber, matrix and fiber/matrix interface was based on steady state dynamic crack growth analyses accounting for rate dependencies of composite phases. Uniaxial tensile stress-strain curves of the resulting impact resistant ECCs were experimentally determined for strain rates ranging from 10-5 to 10-1 s-1. Drop weight tower test on impact resistant ECC panels and beams were also conducted. Damage characteristics, load and energy absorption capacities, and response to repeated impacts, were studied.
