“…In addition, they demonstrated that computing the energy dissipation in both media provides a new comprehensive theoretical view of the fluid transients phenomenon. Andrade et al (2023b) have also employed the internal variables theory to produce an alternative water-hammer model for describing fluid transients in metallic pipes undergoing (visco)plastic deformations. Although the theoretical framework is the same for both viscoelastic and viscoplastic mechanical behaviors, the particular form of the constitutive equations for each of these material's responses renders highly distinguishable mechanical effects.…”
