Structural Component Fatigue Testing Machine

Primarily used for testing metal and non-metal materials, components, structural parts, and standard parts—especially new materials such as ultra-high-strength steel, titanium alloys, and reinforced synthetic fibers—to determine their fatigue performance parameters, fatigue life, cyclic elastic modulus, and fatigue crack propagation rate under tension, compression, fatigue, low-cycle fatigue, crack propagation, fracture mechanics, real-part testing, simulated testing, and symmetric or asymmetric pulsating alternating load cycling.
