Abstract The experimental results presented in part I provided sufficient information about the behavior of Berea sandstone under a large range of confining pressure. In that article, initial yield and failure surfaces were determined, and a yield and a failure criteria were proposed. Further, a hypoelastic model was given for the initial elastic response of this material, that is, for the response within initial yield surface. This article (part II) contains an elastic-plastic model to deal… CONTINUE READING
