Abstract

The static and dynamic tensile and compressive properties of Colorado Yule marble have been obtained from samples all secured from the same parent slab. Specimens were cored in the three principal directions of this transversely isotropic material, the axis of symmetry having been determined petrographically. Standard quasi-static and creep tests were performed, and both Hopkinson-bar and split-Hopkinson-bar tests were conducted for the collection of data at higher loading rates. Elastic constants evaluated for the material on the basis of the present investigation were compared with corresponding static and dynamic values from a previous series of tests conducted on a large block of Yule marble, and to dynamic constants for the same block determined in a separate investigation by means of wavespeed data secured from embedded crystal transducers. The behavior of Yule marble does not seem to conform to any well-known constitutive relation and is, thus, most easily characterized by suitable sets of experimental data.
