Unreasonable results of composite Tensile Test

Dear colleagues,

I am writting to you regarding an issue in the results i optained from a model of Composite Tensile specimens. I have model the specimens in hypermesh as a Composite based plate model and i applied the fully clamped BC in one side and a load in Y direction (with respect to global coredinate) in the other side. the model is run uner Optistruct solver with nonlinear static analysis without Problem but the results I optained are an unerealistic. The displacements are with very large Amplitude and in Z direction(the load is in Y direction ) ????. I have atteched the model with this

request. can kindly check it and tell me what is wrong ???

Regards

Kouider
