NUMERICAL SIMULATION ON THE TENSILE STRAIN HARDENING BEHAVIOUR OF ENGINEERED CEMENTITIOUS COMPOSITES (ECC)

Numerical simulation for evaluating tensile strain hardening behaviour of engineered cementitious composites (ECC) materials are extremely limited. This paper presents a finite element (FE) model developed to determine the multiple-cracking and ECC under uniaxial tension. A nonlinear FE program, ATENA was used in this study. constitutive law based on individual crack-based derived by traction-separation relationship, or also known as function implemented model. Model calibration with parameter modifications were illustrated. The final result predicts accurately experiment stress curves, including response, ultimate strength capacity. includes validation from specimens tested various researchers. It has found that accuracy is improved lowering crack opening displacement corresponds first cracking. finding study would be useful future further parametric analyses structural optimization design members.
