OK. Time for one more Paint-piece of art of mine.
The function which describes E will be predetermined .. From experimental data. I still have no clue which mathematical level of approximation I'll use.. (Linear, 2nd order polynomials, some step funciton...whatever)
In the example that I...
I really appreciate your prompt responds. Thank you for that.
Before closing the topic I have to make everything clear, if possible.
I have a 'interphase material' which becomes progressively less stiffer. So starting from material 1. with really high stiffness (i.g. E=1000000) , via...
I hope I managed to show how I came up to this silly idea.
But even there I have the problems with this x0,x1,deltx .. Can deformation gradient provide us info about new position of the point? If I remember correct from the Continuum Mechanics classes, the answer is NO!? (F gives the ratio...
Dear muzials,
first of all I have to correct myself and say that by F(3,3) I meant F with dimension 3x3 with all its elements already known.
I was going the opposite way of course. The purpose of my study is estimating the values/functions of parameters. But let us take it like it's not a...
Dear,
I have a task to model the behaviour of certain interphase material. Let's say that functions which describe the change of material parameters are known.
i.g. change of the Young's modulus as function of distance from neighbouring material (or (0,0) origin) - PAR=PAR(x)...
