Dear all,
I have been trying to model pull of single yarn in abaqus and model is responding. i got a problem now. I am applying velocity in one of the yarn and I am pulling it out.Boundary conditions are fixed on both the sides. to calculate the force that is being applied on to the fabric, pull out force, I summed up all the reaction quantites RF1,RF2,RF3 and i plotted it against displacement. but the force is touching zero sometimes. i dont know the reason. what could it be?
P.S. : I have attached my pull out graph also.
regards
