  Hey, I am doing tensile test simulation on carbon fiber epoxy resin composite panel. In the standard test, a rate of displacement 2mm/min is applied, should I apply 2mm displacement in static structural or should I consider displacement for one second?

  nYou can apply the 2 mm displacement in 1 second in Static Structural.n

  nI am trying to figure out the tensile strength of the composite panel and how does fiber misalignment influences it. The panel here is 2mm thick consisting of 0/4/4/0 degree plies each of 0.5mm. Using ACP PrePost, I applied multiple failure criterias to observe where exactly the ply fractures. For the standard displacement i.e. 2mm, I am getting the following failure contour for the top ply:nI don't know what does th, e1t and e2t stands for. I think from the legend it is safe to conclude that the entire red region has fractured. To find the localised region of failure, Should I reduce the applied displacement ?nLastly, I wanted inquire about the stresses I am getting. In my opinion, these values are much higher.nWhat do you think about the stress contour? Have I messed up the boundary conditions ? (I applied fixed support on one tab, applied displacement along x on the other, and constrained the panel displacement in z and y directions)nn
