Development of Methods to Determine the Hugoniot Equation-of-State of Concrete
Abstract
Methods used to determine the Hugoniot equation-of-state were experimentally evaluated for structural concrete having 3/4 in. (prototype) and 1/8 in. (modeled) aggregate sizes. Shock wave simulations were conducted using a two-dimensional shock-wave propagation computer code. Results showed that Hugoniot tests could be conducted on the prototype concrete within acceptable tolerances of experimental error. Results also showed that the Hugoniot equation-of-state of the prototype concrete can be matched with a modeled concrete mixture. Shock propagation simulations of a computer modeled prototype concrete were found to closely reproduce the Hugoniot of the prototype. In- material stress and particle velocity gage methods and Lagrangian data analysis techniques are discussed in detail. Experimental and simulated shock profiles and material response curves are also presented and discussed in this report. Recommendations pertaining to important experimental design criteria as well as for further study are also included.
