Observations of grain size sensitive power law creep of olivine aggregates over a large range of lattice-preferred orientation strength

Abstract:

Grain size sensitive (GSS) power law creep of San Carlos olivine aggregates was investigated by comparing strain rates measured in laboratory deformation experiments to strain rates determined from a micromechanical model of intragranular dislocation processes. The plastic flow behavior of olivine aggregates due solely to intragranular slip was determined using flow laws for olivine single crystals in combination with grain orientations measured by electron backscatter diffraction. Measured s...
