Hi,
I want to derive the rate form of the consitutive relation for hypoelastic material:
Jaumann stress rate=L:D
where L is a fourth order modulus tensor and D is the rate of deformation.
Most papers that I have seen begin with this expression. But I would like to know how to arrive at this equation.
Any suggestion?
Thanks
Brunda

It disscussed hypoplasticity but the main development are the same i guess.
