Median Servo-Hydraulic Testing Machine




This range of test systems meets practically all the requirements of metals and composites testing for strength, durability and toughness. It is backed up with a wide choice of appropriate application software, transducers and accessories that satisfy the requirements of most standard test practices applicable to such tests. These accessories include room and elevated temperature testing of metals for tension and compression properties, low and high-cycle fatigue, fracture and fatigue crack growth, testing of composites under ambient and controlled environment for shear, tension/compression and fatigue and testing of joints and fasteners for strength and durability under a wide range of loading conditions, including constant amplitude, programmed block loading and simulated service loading.
