The shear relaxation modulus, \(G_{12}(t)\), for an orthotropic lamina is idealized, as shown in Figure 8.30. Find the corresponding equations for the shear storage modulus, \(G_{12}^{\prime}(\omega)\) and the shear loss modulus, \(G_{12}^{\prime \prime}(\omega)\), and draw sketches of both parts of the complex modulus in the frequency domain.
