Problem 1: Part 12: Trial elastic stress[edit | edit source]

In the radial return algorithm, we define a trial elastic state as

where are the stress and strain at and are the values at . Show that, if the elastic response of the material is linear, equation (2) can be written as

From equation (2)


Hence shown.
