Question:
The shear creep compliance, \(S_{66}(t)\) for a unidirectional viscoelastic composite is given by \(S_{66}(t)=\gamma_{12}(t) / \tau_{12}\), where \(\gamma_{12}(t)\) is the time-dependent shear creep strain and \(\tau_{12}\) is the constant shear stress. If \(S_{66}(t)\) can be approximated by a power law as \(S_{66}(t)=a t^{b}\), where \(a\) and \(b\) are material constants and \(t\) is time, determine the "constant loading rate compliance" \(U_{66}(t)=\gamma_{12}(t) / \tau_{12}(t)\), where the shear stress is due to a constant loading rate, so that \(\tau_{12}(t)=K t\), where \(K\) is a constant.
