We present a 3D-RSWEI characterization of a polyvinyl alcohol phantom with applied uniaxial stretch at multiple transducer tilt angles (0°, 15°, 30°, and 45°), building on previous work [1]. We have observed shear horizontal (SH) and complex shear vertical (SV) wave mode propagation at large stretch ratios and at 15° and 30° of tilt. We have compared analytically calculated shear wave speeds assuming an Isihara material model to experimentally measured speeds in the PVA phantom to re-derive estimates of uniaxial stretch ratios. This analysis indicates the potential for 3D-RSWEI in higher order nonlinear elasticity characterization methods.
