Do I retrofit or replace my Universal Testing machine ? By: Richard Gedney, Founder and President, ADMET Inc. When Testing metals, the primary function of dual-acting piston that moves the crosshead a Testing machine is to generate a stress- up or down. However, most static hydraulic strain curve. (Figure 1) Once the diagram is Testing machines have a single acting piston complete, you can use a pencil and straight or ram. In a manually operated machine , the edge or a computer algorithm to calculate operator adjusts the orifice of a pressure yield strength, Young's modulus, tensile compensated needle valve to control the rate strength and total elongation. of loading. In a closed-loop hydraulic servo system, the needle valve is replaced by an electrically operated servovalve for precise control.
