Abstract: The progressive failure of slopes is often induced by drawdown and strain-softening of the soil. Thus, the stability level of a strain-softening slope under drawdown conditions should be evaluated while considering progressive failure. A simplified…

Abstract: The strain-induced softening of thermoplastic polyurethane elastomers (TPUs), known as the Mullins effect, arises from their multi-phase structure. We used the combination of small- and wide- angle X-ray scattering (SAXS/WAXS) during in situ repeated tensile…
