maxwell

bulk f

bulk modulus, K

poisson f

Poisson’s ratio, v

shear f

shear modulus, G

young f

Young’s modulus, E

viscosity f

dynamic viscosity, η

Notes:

• Only one of the two options is required to define the elasticity: bulk modulus K and shear modulus G, or Young’s modulus E and Poisson’s ratio v.
• The creep behavior is triggered by deviatoric stress, while the volumetric behavior does not consider creep.
