Fatigue damage in composite cylinders
Polymer Composites, 2009 AbstractIn this study, optimal angle‐ply orientation of symmetric composite cylinders under fatigue loading is investigated. The fiber‐reinforced plastic cylinders were manufactured from E‐glass/epoxy. The layers were manufactured symmetrically in [±75°]2, [±60°]2, [±55°]2, and [±45°]2 orientations.

Linear Damage Rule Life Prediction for Stress Controlled Fatigue-Creep Interaction of Aluminum Alloys [PDF]
Engineering and Technology Journal, 2012 The fatigue-creep interaction performance of 5086 and 6061-T651 aluminum alloys were investigated for specimens tested under control stress rotating bending at a stress ratio R=-1 and 250°C temperature. The fatigue endurance limit for both alloys reduced

A multiaxial incremental fatigue damage formulation using nested damage surfaces [PDF]
Fracture and Structural Integrity, 2016 Multiaxial fatigue damage calculations under non-proportional variable amplitude loadings still remains a quite challenging task in practical applications, in part because most fatigue models require cycle identification and counting to single out ...

High temperature fatigue characteristics of P/M and hot-forged W-Re and TZM for X-ray target of CT scanner [PDF]
, 2018 The fatigue strengths at 1000 °C of layered W-Re/TZM, bulk W-Re and bulk TZM for x-ray target materials were successfully evaluated under load-controlled four-point bending by introducing a fatigue failure criterion as twotimes increase of initial ...
