A Rheological Model of Sandstones considering Response to Thermal Treatment by Xingang Wang, Lei Huang, Junrong Zhang

“…This response, however, has not yet been fully considered in the existing rheological constitutive models for sandstones. In order to experimentally investigate such responses and establish the associated rheological constitutive model, this study considers the sandstone specimens which have been thermally treated under different temperatures. …”
