Material modeling of hyperelastic silicone adhesives considering stiffness reduction

Predicting the hyperelastic behavior and the stiffness reduction of adhesive is essential for the economical dimensioning of load‐bearing bonds in the field of glass façade construction. The typical hyperelastic behavior can be modeled by using one of well‐known hyperelastic models. In addition, a new variable for modeling stiffness reduction was defined. A new material model based on the Ogden model for representing hyperelasticity and stiffness reduction was defined.
