    Abstract: An apparatus is provided having an active material forming a surface thereof in contact with a rheological fluid. The active material is controllable to vary a surface geometry thereof between a rough or nonsmooth surface geometry to increase drag, and achieve an increase in stress transmitted through the fluid, when a field is applied, while allowing a smooth surface geometry and an associated reduction in stress transmitted through the fluid when the field is removed. A method of enhancing performance of an apparatus that includes a rheological fluid is also provided.

    Abstract: A fixture device generally includes a base member, a reconfigurable pad comprising a shape memory material configured to selectively conform to a surface contour of a workpiece, and a thermoelectric unit in operative communication with the shape memory material of the reconfigurable pad. A process for operating a fixture device includes passing a current in a first direction through a thermoelectric unit in operative communication with a reconfigurable pad in an amount effective to heat a shape memory material therein to or above a shape setting temperature, contacting a surface of a workpiece with the reconfigurable pad, cooling the shape memory material below the shape setting temperature, and fixturing the workpiece with the fixture device.
