Determination of energy consumption in the fracture plane of Ultra High Toughness Cementitious Composite with direct tension test

In this paper, the energy consumption in the fracture plane of Ultra High Toughness Cementitious Composite was analyzed with double-edge notched plates under direct tension. The results showed that monitoring elongation and retraction of the notched regions could effectively separate the localized crack from other multiple cracks, and the softening curve could be drawn accordingly. With the softening curve, the fracture energy due to fiber bridging Gb and the fracture energy GF were calculated. This work provides a thought more than the detailed results to separate the single fracture crack from other multiple fine cracks of pseudo strain hardening materials.
