Læringsmål

Viden

Knowledge

  • Should have basic knowledge about fracture mechanics analysis in order to establish criteria for crack initiation and crack growth.
  • Should have knowledge about application of fracture mechanics in engineering applications.
  • Should have knowledge about models for analysis of fatigue i.e. models for crack growth and influence of loading sequences.
  • Should have knowledge about application of fatigue analysis in engineering applications.

Færdigheder

Skills

  • Should understand the stress and strain variations near a crack tip.
  • Should understand and be able to perform quantitative and qualitative analysis of stress intensity factors.
  • Should understand the crack driving force based on energy analysis.
  • Should understand the influence of plasticity in the fracture process.
  • Should understand the basic models for crack growth.
  • Should understand different scenarios in fatigue analysis e.g. stress or strain driven, low- or high cycle fatigue.
  • Should understand and be able to use methods for analysis of stress variations (e.g. Rain-Flow counting).
  • Should understand and be able to use Palmgren-Miners damage model.
  • Should be able to calculate the lifetime of welded components.
  • Use correct professional terminology

Kompetencer

Competencies

  • Should be able to participate in analysis of risk of fracture in engineering structures and in a dialog on structural modifications in order to reduce the risk of fracture.
  • Should be able to model, calculate and communicate fatigue analysis of welded structures and participate in a dialog of fatigue analysis of other structural components.
