WebFigure 13 shows a plot of cavity volume versus the downward displacement of the rigid body in Step 4 of the Abaqus/Standard analysis and Step 2 of the Abaqus/Explicit analysis. The cavity pressure and the cavity … WebThe inflator capability in ABAQUS/Explicit is suited for modeling the flow characteristics of inflators used for airbag systems. You must associate the inflator definition with a name. You specify the reference node of the fluid cavity that the inflator will fill with gas. A single fluid cavity can have any number of inflators.
WebIf a large amount of fluid is removed from a cavity or the material surrounding the cavity is very flexible, the cavity may partially collapse and portions of the cavity walls may contact each other (see Figure … WebThis parameter applies only to Abaqus/Explicit analyses. Use this parameter to define the magnitude of the minimum volume for the fluid cavity. If the volume of the cavity (which …
