Lattice structures are lightweight engineering components suitable for a great variety of applications, including those in which the structural integrity under vibration fatigue is paramount importance. In this work, we experimentally and numerically investigate dynamic response two distinct lattice configurations, terms damage life. Specifically, Face-Centered-Cubic (FCC) Diamond lattice-based...

• Multiaxial fatigue models for notches are analysed. The geometry is an infinite plate with a circular hole. evolution of the predictions increasing hole radius not monotonic. This non-monotonic observed experimentally. work shows analysis several multiaxial notches: Navarro-Rios’ model, which analyses interaction between crack and its associated plastic zone material microstructural barriers,...
