  4. Abstract:
  5. This paper evaluates the applicability of several concrete models to simulate the behavior of concrete elements under monotonic and cyclic loadings. Several robust constitutive models based on the combination of plasticity and continuum damage or plasticity and smeared crack approach are selected. The behavior of one concrete element is evaluated under different uniaxial compression, uniaxial tension, biaxial compression, biaxial tension, biaxial compression–tension, and triaxial compression loads. Then, the applicability of the concrete models is investigated for two flexural beams under cyclic loading. Five concrete models available in the versatile finite element-based software LS-DYNA are selected, including Winfrith, CSCM, RHT, KCC, and CDPM. The prepeak, peak, and postpeak behaviors of all selected models are presented, including initial stiffness, peak strength, strain at peak strength, postpeak stiffness, and failure strain. © 2021 John Wiley & Sons, Ltd
