Hello

Im looking for a model of a material named TangoBlack Fullcure 930 (a rapid prototyping material).

The main problem is that I dont have a lot of data about it (Tensile strenght, elongation at break, modulus of elasticity...).

Anyway, I found two papers on the internet from people who did some tests on the material (I attach them to this post).

Here is my problem :

For the first model : C10 = 6.7664 e-2 MPa and C01 = -9.1133 e-2 MPa. The other model is C10 = 9.1054 e-2 MPa and C01 = 5.3337 e-3 MPa.

In the first model, the sum of C01 and C10 is negative, so my simulation tools doesnt accept those parameters !

The second models seems to be working but it doesnt correspond to the experimental data from the first model...

Could you help me figuring the right model for this material ?

Thank you !
