Accurate replication of soft tissue properties is essential for the development car crash test dummy skin to ensure precision biomechanical injury data. However, intricacy multi-layer poses challenges in standardizing and testing materials emulate properties. This study presents a comprehensive analysis compressive mechanical both single multi-layered tissues materials, aiming enhance biofidelity skin. We presented one-term Ogden hyperelastic models generalized Maxwell viscoelastic single-layer tissues, as well materials. The comparative results indicate that existing material fails fully consider strain-rate-dependent characteristic tissue. Furthermore, exhibited ~3 times shorter relaxation ~2–3 lower stress decay rates compared suggesting less viscous nature. provides an accurate representation mechanics under quasi-static loading. findings are instrumental novel bionic or structures more precisely replicate thereby enhancing accuracy reliability dummies.
