Hello
at first thanks for your help.
My simualtion is running now with partially good results.
For the layer one, which all the pictures refer to, i calculated a stress in x-direction of 223,5 N/mm^2 and in y- direction of -18,9 N/mm^2 with the Classic Laminat Theory. The stress in z-direction is 0, which fits to my calculations.
These results apprear in big parts of the tube, but in some parts their value is the right value multiplicated with -1.
Is this because of the orthotropic material properties of the CFRP?
To my constraints: the nodes from z= 0 to z = 30 mm are constrained with all six degress of freedom. The nodes at the other end are coupled by RBE3 with a master node in which the torque (torque is the only load) is lead in. By the RBE3 command i coupled all degress of freedom from the slave nodes with the master node.
Thanks for your help!
