Fracture Mechanics
The field of research called fracture mechanics aims at quantifying the risk of fracture in components and structures containing defects. The mathematical equations relate the measured material fracture toughness to the applied load and defect size, offering a quantitative link between defect inspection, materials technology and design.

SINTEF Materials and Chemistry, Fracture MechanicsThe main goal for SINTEF is to continuously improve the procedures for fracture mechanics testing and engineering critical assessment analysis. It is important to implement our knowledge in industry and  develop more accurate and simplified assessment methods that can be used as effective tools.

Our strengths are:

  • Fracture assessment of pipelines.
  • Welding technology (incl. Hyperbaric welding) and residual stress simulation.
  • Mechanical testing and analysis; from small-scale testing to full-scale testing/verification. 
  • A fully equipped workshop with experienced personnel provides test specimen preparation for many types of materials and testing requirements.
  • High capacity and quality of numerical simulations. Numerical simulations offer a unique possibility to quantify and examine the relationship between microstructure related material properties and the mechanical behaviour and is therefore a central element in the research activities. 
  • There is a large group of experts in fracture mechanics available in Trondheim, as we also include professors from NTNU. This makes SINTEF to an attractive research partner for industry. SINTEF also performs a lot of standardized fracture mechanics testing and analysis in qualification projects. The main reason why industry should go to SINTEF for these kinds of activities is quality combined with expert advice. Expert advice is invaluable when the results are below or on the edge of the requirements of the specifications.
