I have configured a 28 layer unidirectional laminate of T300/PR319 material.
When I try to draw the failure body for the first ply and last ply, following error occurs as " there is at least one zero strength value for material T300/PR319".
For additional inormation, I have considered only the axial force and moment i.e. (Fx and Mx)
How can get this error solved?
