Necking

SergioSergio
Hi, in the calculix for win page there is a picture of what I guess is a traction test simulated. I can see the clasic"necking" in the middle for ductile materials, but my simulations using no lineal properties always shows that the strain (and deformation) are constant along the calibrated diameter. Any idea how this necking was achived?

    From my knowledge, the common approach is to provoke the necking by a little node distortion to force the localisation.
