Abstract

Fatigue testing is an essential tool in mechanical engineering to evaluate the fatigue lives and strength of materials and components under cyclic loading. Two-dimensional (2D) fatigue testing machines enable the application of complex multiaxial loads for advanced analysis. This paper provides a comprehensive review of the design and optimization of 2D fatigue testing machines. The machine components including actuators, load cells, specimen grips, and fixtures are analyzed. Key design factors such as stiffness, alignment, load application, and control systems are discussed in detail. Finite element analysis optimization techniques are presented for frame stiffness and vibration control. Advanced features such as biaxial loading capabilities, extensometer integration, and environmental chambers are also covered. Recommendations are provided for best practices in 2D fatigue testing machine design, instrumentation, calibration, and validation. The goal is to equip mechanical engineers with knowledge to develop state-of-the-art 2D fatigue testing systems for reliable high-fidelity fatigue characterization.
