(Top) Fitted fluctuating stress amplitude $\Delta \tau$ in units of ${\tau }_{\max }$ as a function of the “net shear” $\Delta V$; symbols as in Fig. 2. (Bottom) Schematic of the fluctuating shear stress superimposed on the continuum ${\tau }_{xy}$. The dashed line shows the quadratic fit used for the integration.Reuse & Permissions
