Hello Everyone

I'm doing my research work on Tension after impact on composite laminates. I have done the simulation in Abaqus with continuum shell element. I gave orthotropic material properties with strength values and fracture energy. I used ABAQUS inbuilt hashin model. After my simulation when I see the results, the elements are stretching instead of sudden failure.  Load vs displacement curve should fall suddenly but here it behaves like a plastic material. Even when I simple tension test also elements are stretching. Can anyone pls help to rectify this problem. Thank you​​​​​​​
