• Fatigue Delamination Prediction using a Cohesive Zone Model and its Latest Extension to Multi-Level Block Loading
  E. Lindgaard (Aalborg University, DEN)

Invitation

Modeling dynamics, fatigue, and fracture are relevant to many industrial applications often aimed at improving the reliability of the final product. Applications, covering the modeling of drop-test of small devices, fatigue simulations for lifetime predictions of automotive, aerospace, and other industrial products, and fracture simulations aimed for e.g., crashworthiness predictions.

Despite its importance, it is still considered a challenging task to get accurate predictions for such cases. Dynamic impact loading requires high strain rate material data and well-defined loading conditions. Fatigue lifetime predictions require complex damage evolution laws that often depend on a large number of intrinsic materials and loading parameters. Fracture models often require fine mesh resolutions, care of mesh-sensitive solutions, and hard-to-measure cohesive material laws.

The conference will be hosted at Technical University of Denmark, DTU Wind Energy located at DTU Risø Campus near Roskilde in Denmark. In addition to listening to presentations covering those challenging fields, a tour of DTU Wind Energy’s world-leading composite mechanical testing labs, covering fatigue testing of interfaces and composite material and a tour at the Large Scale Facility, testing fatigue failure of wind turbine blades will be given.

The seminar welcomes participation from every type of organisation – large and small, across all industry sectors. The event is open to both members and non-members of NAFEMS, with members able to attend the event for free towards using three seminar credits, as part of their membership benefits package.

Please also inform interested colleagues - many thanks in advance.
