A novel facility has been developed for elastic-plastic-viscoplastic evaluation of structural materials through the integration of universal servo-hydraulic actuators connected to a standard servo controller and linked to an advisory control system automation package. Significant flexibility in terms of control mode, loading rates and end levels is achieved using the developed software/hardware interfaces. This technology enables complex waveform test profiles while ensuring machine tractability through closed loop control via feedback signals. Functions such as reloading, dwell, loading rate revision and mode switching can be programmed to trigger at any time during the test profile. Actions may target either axial or torsional actuator response since each control channel is fully independent. Signal conditioning and noise reduction for digital data acquisition are accomplished with “onboard” active filtering located on control system equipment as well as by employing post feedback active filtering provided by a commercially available digital dual-channel programmable filter system.
