Abstract: High performance fiber reinforced cementitious composites (HPFRCC) are characterized by multiple cracking and pseudo strain hardening under direct tensile loading. Designing for these properties of HPFRCC and prediction of the tensile behavior is essential for structural applications. In this study, experimentally obtained information on the fiber bridging stress-crack opening relationship is used to assess the potential for multiple cracking and strain hardening behavior of HPFRCC in uniaxial tension.
This paper proposes a method to simulate the displacement-controlled uniaxial tension test of HPFRCC using information on stress-crack opening relationship. The multiple cracking phenomenon in the strain hardening stage is captured in the simulation results and characteristics of multiple cracking such as width and spacing can be obtained.
