Greater Ψ values indicate a higher material recovery and smaller values represent the opposite effect, i.e., the higher Ψ, higher delayed elastic recovery will take place and vice versa.
Valores altos de Ψ, indican una mayor recuperación del material y valores pequeños representan el efecto contrario, esto es, a mayor Ψ habrá mayor recuperación elástica retardada y viceversa.
