Abstract The PRISMS-Fatigue open-source framework for simulation-based analysis of microstructural influences on fatigue resistance polycrystalline metals and alloys is presented here. uses the crystal plasticity finite element method as its microstructure tool provides a highly efficient, scalable, flexible, easy-to-use ICME community platform. linked to different software instantiate microstr...

Deformation and failure under multiaxial stresses-a survey of laboratory techniques and experimental-data-by-W, J. Evans National Gas Turbine Establishment SUMMARY A survey has been made of techniques for producing multiaxial stress conditions on a laboratory scale and it is concluded that one of the more suitable systems is combined tension-torsion of thin-walled tubes. Experimentally this tec...

Despite the importance of multiaxial failure of trabecular bone in many biomechanical applications, to date no complete multiaxial failure criterion for human trabecular bone has been developed. By using experimentally validated nonlinear high-resolution, micromechanical finite-element models as a surrogate for multiaxial loading experiments, we determined the three-dimensional normal strain yi...

In the present paper, a novel criterion for fatigue life assessment of engineering components under multiaxial low-cycle regime is proposed. The criterion, named Refined Equivalent Deformation (RED) allows to take into account, when load non-proportional, strength decrease experimentally observed those metals sensitive non-proportionality. applied two different (304 stainless steel and 6061 alu...

Malalignment of the tibial tray in total knee arthroplasty has been linked to several complications including tibial tray subsidence, leading to revision surgery. However, quantitative biomechanical evidence to directly support the mechanism of failure is not available. We developed a model to study tibial tray micromotion and subsidence in vitro under multiaxial physiological loading condition...
