Investigation of the Endochronic Concrete Model.

Abstract

This report describes a continuing evaluation effort on the hysteretic-fracturing endochronic concrete model developed by Bazant and Schieh. The ability of the model to synthesize concrete behavior of a variety of standard and nonstandard load paths is studied through comparisons made with the triaxial test data on plain concrete recently generted at New Mexico State University. The model provided a reasonable match to the experimental data. A Three-dimensional version of the endochronic algorithm was developed. A scheme was proposed which would allow for inclusion of high strain rate effects in the model. Simplified versions of the model which would significantly reduce computer storage requirements were devised and investigated. (Author)
