Abstract:
The effect of the parameters of a model, namely flow ratio (Κ) and angle of friction (β), is analyzed numerically on high-strength concrete (HSC) under a time-dependent pressure load. HSC, with a compressive strength of 120 MPa under static loading, when simulated under a rate of loading of 1100 GPa/s, shows an ultimate compressive strength ranging from 133 MPa to 160 MPa. The dynamic stress and strain of HSC is proportional to the flow ratio and angle of friction. Multiple regression equations have been established to define the relationship between model parameters and dynamic strength, which are applicable for flow ratios between 0.80 and 1.00 and an angle of friction between 50° and 65°.
