Hi Everyone, Let say I know the force/cm versus elongation relationship for a flat band, and I combine this with the same type band in the perpendicular reaction (crossing each other). If I apply a point force in the middle of the intersection between the two points how do I calculate how...

Hi everyone, So I have a set of relaxation data and creep data for a solid polymer that I want to analyse. In the relaxation I use the Prony series derived from the generalized maxwell equation (incl a spring) and get a very nice fit. My question is if I should use the same to model the...

Hi again, Yep that did it, thanks a lot, but now I have run into another problem. I run my equations and get the following stopping criteria: No solution found. fsolve stopped because the problem appears regular as measured by the gradient, but the vector of function values is not near...

Hi everyone, I am a MATLAB newbie and am having some problems getting fsolve to work. I tried using the example given in the help section but it keeps saying that my function (lambda_y1) since that is the first one it finds is unknown. My functions are generated like this (sorry for the...

Homework Statement Not sure this is the right place for this but here it goes... I am trying to figure out the derivation of the force elongation relationship of the maxwell elements in parallel in order to derive it for the Kelvin Voigt elements in series. I have attached the material that I...
