Abstract
An apparatus () for applying at least one load to a specimen () according to one embodiment of the invention may comprise a mass (). An actuator () mounted to the specimen () and operatively associated with the mass () moves the mass () along a linear displacement path () that is perpendicular to a longitudinal axis of the specimen (). A control system () operatively associated with the actuator () operates the actuator () to reciprocate the mass () along the linear displacement path () at a reciprocating frequency, the reciprocating frequency being about equal to a resonance frequency of the specimen () in a test configuration.
