This calculator implements the K&C (Karagozian & Case) Concrete Damage Model calibration specifically for Ultra-High Performance Concrete (UHPC). The model uses empirical equations to predict triaxial behavior without requiring laboratory triaxial test data.
Based on: Xu M, Wille K. Calibration of K&C Concrete Model for UHPC in LS-DYNA. Advanced Materials Research. 2015;1081:254-259. doi:10.4028/www.scientific.net/AMR.1081.254
Valid Range: f'c = 150-250 MPa (calibrated for UHPC materials). The calibration uses empirical models from Attard & Setunge (1996) and Samani & Attard (2012).
Note: This calibration provides better agreement with UHPC test data compared to automatic K&C parameter generation. Results should be validated against experimental data for critical applications.
📐 Unit System: mm-s-tonne-N-MPa (MPa for pressure/stress, ton/mm³ for density)
