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.
