What are the most important modeling techniques and Abaqus options to use to accurately predict collapse of rubber hose having vacuum loading? I am currently using Hyperelastic (nonlinear) material data and Hybrid formulation elements. What other techniques and options are recommended? The hose geometry typically has one or more bends and a constant material thickness (±5%). To keep it simple, the material is isotropic and one type such as EPDM (so, not multi-layer).
