Accurately reproduce experimental results! The concrete constitutive laws use KCC, Winfrith, and CSCM!

We conducted an impact analysis of a reinforced concrete beam using three types of concrete constitutive laws and validated the simulation accuracy by comparing it with experimental results. The concrete constitutive laws used were KCC (MAT_072R3), Winfrith (MAT_084-085), and CSCM (MAT_159). The Winfrith model allows for the visualization of crack patterns, and the analysis results confirmed the direction of the cracks. Additionally, when examining the impact analysis at an impact velocity of 9 m/s using the KCC model, it was found that the typical impact damage behavior of the beam was well represented. 【Concrete Constitutive Laws Used】 ■KCC (MAT_072R3) ■Winfrith (MAT_084-085) ■CSCM (MAT_159) *For more details, please refer to the related links or feel free to contact us.

basic information

【Analysis Results】 ■Impact load due to drop hammer impact - It is evident that the three types of models accurately reproduce the experimental results. ■Damage characteristics of beams according to concrete constitutive laws - The Winfrith model can depict the cracking behavior. - The analysis results allow for confirmation of the direction of the cracks. ■Impact analysis at a drop hammer impact speed of 9 m/s - The results of the investigation using the KCC model show that the typical impact damage behavior of the beam is well represented. *For more details, please refer to the related links or feel free to contact us.
