If storage and loss modulus relate to thickness and thinness, why does modulus crossover show storage modulus increasing and vice versa when a material is being shear-thinned?
Post Body
The title pretty much covers it. When a material in melt phase is being shear thinned with oscillatory motion in a rotational rheometer, you see some materials shear thin as the angular frequency increases.
However, when you see modulus crossover happen on the same material, it’s actually the storage modulus rising above the loss modulus, which to me seems like that would mean it’s getting thicker.
