Impact Testing  WMTR
202197 Impact tests are used in studying the toughness of material. A material's toughness is a factor of its ability to absorb energy during plastic deformation. Brittle materials have low toughness as a result of the small amount of plastic deformation that they can endure. The impact value of a material can also change with temperature.

Aggregate Demand Definition (4 Components and Formula)
202124 Thus, when adjusted for the price level, GDP and aggregate demand align in the longrun. In the longrun, there is no difference in value between the two. With that said, there is a clear difference in terminology. For instance, when describing aggregate demand, we are referring to total demand.
