3. Life prediction and mechanisms for the initiation and growth of short cracks under fretting fatigue loading
Abstract : Fretting fatigue is a damage process that may arise in engineering applications where small cyclic relative displacements develop inside contacts leading to detrimental effects on the material fatigue properties. Fretting is located in regions not easily accessible, which makes it a dangerous phenomenon. READ MORE

4. Continuum models and numerical methods for fretting
Abstract : This study is concerned with continuum models and numerical methods for wear, frictional heat and damage. Of special interest are so called fretting phenomena. Fretting occurs when two bodies in contact experience small periodic, relative motion which leads to wear and the promoted initiation of fatigue cracks. READ MORE

5. Surface Integrity of Broached Inconel 718 and Influence of Thermal Exposure
Abstract : Inconel 718 is a nickel-based superalloy that is extensively used as a disc material in gas turbine engines. The service life of gas turbine discs is normally governed by the modes of material degradation and fatigue failure since they work mostly at high temperatures and are subjected to cyclic mechanical loadings.
