An expandable insert assembly, method of making the same, and a vehicle structure are disclosed. A structure may include a wall defining at least a portion of a cavity, with the wall including an installation surface for the insert. The insert may include a substrate configured to be secured to the installation surface, with the substrate having a stiffness allowing the substrate to deflect relative to an initial shape. The insert further includes a plurality of discrete expandable elements secured to the substrate adjacent the installation surface. Each of the discrete expandable elements are formed of an expandable material and are secured to the substrate such that they do not affect the stiffness of the substrate prior to expansion of the expandable elements. |
