Hi to everybody,
I'm Marco and I'm new to the forum. I graduated in Aerospace Engineering Bachelor Degree and this year I will graduate in the Master Degree in Aerospace Engineering.
I have to simulate the instability of an elastic band, when you twist it and and it curls up on itself. I searched many informations on internet and I did a lot of tests but I'm very far to simulate a simil behavior. Starting from the beginning, the shape of the elastic band is a parallelepiped, so I simulate it in a 2-dimensional way. I have defined an hyperelastic material with C10 and C01 parameters with the theory of Mooney-Rivlin MATHE. Then, I have doubts on which property I can define to have displacements out of the plane, since I want to rotate the free end. Can someone give me some advices?
Thank you very much,
Marco
