Abstract

This paper presents a simple mathematical model that can be used in engineering practice to estimate the stress–strain behavior of very strong limestones and dolomites (σc > 100 MPa) subjected to uniaxial compression. This model is developed using the canonical form of Haldane’s distribution function. To estimate the stress–strain response using the proposed model, sophisticated stiff load frames are not needed. It is argued that only a simple uniaxial tester (with a hand pump) for one point measurement at a small stress and Schmidt hammer are required to estimate stress–strain response from zero strain/zero stress up to failure.
