[Grammar] Of the different facets

[mutena24]

Hello all,

Could someone explain me the underlined:

"Of the different facets of a material’s behaviour, rheological behaviour is needed for the Mechanics of Materials."

Does it mean "rheological behaviour of the different facets of a material’s behaviour"?

Thanks.

No. It means that, when one is considering the mechanics of a material, then from all of the different facets of that material's behaviour, one has to focus on the rheological behaviour of that material.
