Normalized strength evolution of previous studies with hydrate saturation at strain rate Rεa = 1%/min (Masui et al. 2005, 2007; Miyazaki et al. 2007, 2011a, b; Yun et al. 2007; Hyodo et al. 2013b, 2017; Yoneda et al. 2015a, b, 2017, 2019a, 2021, 2022; Choi et al. 2018; Nakata et al. 2018; Nakashima 2019; Priest and Hayley 2019; Xu et al. 2022). Plots are categorized by effective confining stress. The solid lines are predicted values based on the proposed Eq. (7)
