A bending apparatus for a sample is disclosed. The bending apparatus includes a translation mechanism that translates a vertical displacement/force into a horizontal displacement/force for bending. Components of the bending apparatus are fabricated from a strong, radiolucent material. In these ways, the bending apparatus is compatible with micro-CT imaging, and as such, may be used to bend a sample during imaging. In a particular application, the bending apparatus may be used to measure biomechanical properties of a bone, such as bone strength, bone material properties, fracture toughness, and fracture propagation.

An actuator control system, mechanical testing system, and method for adaptive control of an actuator of a mechanical testing device is provided. The method includes applying a mechanical load to the specimen with the actuator, resulting in receiving a load sensor signal from a load sensor and a displacement sensor signal from a displacement sensor, deriving lumped dynamics of the mechanical testing device by analyzing a phase and magnitude relationship between a current command of a motor of the mechanical testing device and a resultant deflection of the specimen, and controlling the actuator based on the derived lumped dynamics of the mechanical testing device such that the controlling results in a stable motion.
