Fracture evaluation of ultra-high-performance fiber reinforced concrete (UHPFRC)

The development of numerical simulation for Ultra-high-performance concrete (UHPC) and fiber-reinforced concretes (UHPFRC) is fundamental the design construction related structures. simplified engineering stress-strain relationship input values are necessary in finite element modeling. Four-linear curves modified Kent–Park model were proposed to describe tensile compressive relationship, respectively. An attempt was made simulate fracture UHPC UHPFRC using damaged plasticity deletion strategies. predicted behaviors successfully validated by test results literature. For a better understanding mechanical behavior exposed biaxial loadings, mixed-mode crack propagation on double-notched specimens combined shear-tensile shear-compressive forces discussed.
