Redesigning axial-axial (biaxial) cruciform specimens for very high cycle fatigue ultrasonic testing machines
The necessity to increase performances in terms of lifetime and security in mechanical components or structures is the motivation for intense research in fatigue. Applications range from aeronautics to medical devices. With the development of new materials, there is no longer a fatigue limit in the classical sense, where it was accepted that the fatigue limit is the stress level such that there...
متن کاملAccelerated multi-axial fatigue experiments: test rig design and first results
This work describes the design, implementation and first results of a fatigue test rig capable of subjecting cylindrical specimens of different sizes and materials to complex real-life loading conditions. The resulting test rig can be used to combine a rotating bending load with a fluctuating torsional load. Due to a closed electromechanical loop, power consumption is limited and a maximum test...
متن کاملAnalysis of Multi-axial Fatigue Test Data Using a Path-dependent Effective Stress/strain Definition
Multi-axial fatigue life assessment is important in power generation, aerospace, automotive, and many other industries. The newly developed path-dependent multi-axial cycle counting and fatigue life assessment method has been shown effective for some applications. For instance, when stress range is used as the only driving force for fatigue failure, the method correlates high cycle fatigue test...
متن کاملMulti-Axial Failure Models for Fiber-Reinforced Composites
Combined in-phase tension/torsion loading was applied to 8-ply 45° 4 E-glass/epoxy composite shafts under monotonic and fatigue conditions to determine the effects of multi-axial loading on its failure. A damage criterion for multi-axial monotonic loading was proposed considering the contribution of both normal and shear stresses on the plane of failure. The experimental data showed an excellen...
