How to simulate flexible components

Hello everyone ,I am a user of ABAQUS software. Recently I met a problem, I want to simulate a flexible component, just like a rope. when I apply a tensile force ,it generates tensile stress. when I apply a compress force, it does not generate compress stress. For example. For the structure in the attachment, One end applies tensile force another is fixed. Before straightening, the component will not generate stress. How can I complete the job. If you have some idea please share it here, thank you!
