We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

So if my model has a higher modulus than the physical product, then if there were two products in real life (a core with adhesive and a core with higher stiffness due to bonded contact) and we applied the same shear force to them, wouldn't the core with bonded contact, which is stiffer, make less displacement? Or in other words, wouldn't the core with bonded contact have more reaction force for them to make the same displacement? I think the answers to these questions are yes.
 
So shouldn't I find the shear modulus of the core with bonded contact higher than the product with adhesive? Because in ASTM 273, as the slope of force deflection increases, the shear modulus increases and the remaining parameters in the formula are related to the sample size.
