General non-linear materials
WebAug 19, 2024 · The actual stress-strain relationship of structural materials is nonlinear. This paper will give short introduction about material nonlinearity and its usage and … WebImportant materials of this class are Ramberg-Osgood for modeling metal and other ductile materials, and the Duncan-Chang soil model. The nonlinear elastic materials as such do not include strain-rate nor stress-rate in the constitutive equations. It is however possible to add linear viscoelasticity to these materials.

WebIt will be assumed at first that the material is isotropic and homogeneous. The case of an anisotropic elastic material is discussed in Section 6.3. 1 if the small-strain approximation is not made, the stress-strain relationship will be inherently non-linear; the actual strain, Eqn. 4.1.7, involves (non-linear) squares and square-roots of lengths
