Dashpot is missing a relaxation modulus #91

Open akabla opened 4 years ago

akabla commented 4 years ago

There are good reasons for this - G is not very well behaved. However, the response of a dashpot to an imposed ramp and other continuous deformations can't be calculated as a result, at least with the current method.

This became a problem when Eleni tried to breakdown the behaviour the response of a model by extracting stress and strain on each component.

The way RHEOS currently computes things - I don't think it's appropriate to add in the dashpot relaxation modulus.

There are exact cases we can compute by hand but for a more general method we need to implement one or both of the approaches described in my thesis (i.e. integration by parts, differential equation based fits).

@akabla would you like this issue to remain open for further discussion?
