There is no shear stress by definition, and pressure is assumed to be identical on each face (small element). g. Fig. 1: Equilibrium of a small Fluid be considered in hydrostatic calculations. Using the ideal gas equation of state, : After integration between points 1 and 2 and also assuming a constant...

Thus, the constitutive equation for a fluid may be written as: where the dot over the u in the equation indicates differentiation with respect to time and the superscript d denotes "dashpot". By making various combinations of spring and dashpot models, we can simulate the behavior of a viscoelastic material, including stress relaxation and creep.
