Characterization of visco-hyperelastic behavior of open cell polyurethane foam through transient shear testing

Characterization of drying-induced changes in moduli and internal stresses in a constrained gel using laser vibrometry

“…Vibration and wave-based characterization offers a viable alternative for soft materials. [20][21][22][23][24][25][26] For instance, laser vibrometry 21 is shown to characterize dynamic and viscoelastic properties of multiphasic biological tissues such as cartilage considerably faster than conventional techniques. 21 Studies utilized vibration techniques to understand parametric resonances in soft materials and water droplets; 27 develop variable stiffness artificial muscles for vibration absorption; 28 and achieve broadband vibration attenuation using soft materials.…”
