Abstract: The strain rate-dependent mechanical behavior of shale is characterized using triaxial compression tests under a constant confining pressure of 50 MPa and axial strain rates $$\dot{\varepsilon }_{1}$$ε˙1 ranging from 5 × 10−6 s−1 to 1 × 10−3 s−1. This study is conducted… read more here.

Abstract: We introduce a new function, the apparent elastic modulus strain-rate spectrum, Eapp(ε˙)$E_{\mathrm{app}} ( \dot{\varepsilon} )$, for the derivation of lumped parameter constants for Generalized Maxwell (GM) linear viscoelastic models from stress-strain data obtained at various… read more here.
