Résumé
Investigating the mechanical behavior of soft materials through numerical techniques such as finite element analysis, require accurate mathematical models to capture their strain-rate-dependent responses. Stress-based modeling approaches, which represent stress at a given time as a combination of elastic and viscoelastic components, are often complex and typically require numerous parameters for the Prony series representation of the relaxation function. Energy-based methods employing a viscous potential are appealing, however, they have been shown to inadequately capture the rate sensitivity of soft materials with complex stress-strain curves. In this work, we introduce a parameter-based approach based on the principle that material stiffness increases with an increasing rate of loading. A functional relationship between hyperelastic parameters and strain rates is established, allowing the determination of parameters for a given strain rate. The effectiveness of this method is demonstrated by applying it to capture the rate sensitivity of self-healing hydrogel.
