Fatigue life, crack growth and fracture toughness

MET provides fatigue, fracture and crack propagation testing to support engineering decisions in
safety-critical and performance-critical applications.

We support programmes ranging from S–N curve development and material comparison through to fracture
mechanics testing and investigation work, with clear reporting and practical technical input.

Stress/strain cycling programmes to assess fatigue performance under representative loading conditions.

Development of S–N data to support design allowables, comparison studies and qualification.

Crack initiation and propagation studies to support fracture mechanics and durability assessment.

Fracture toughness testing including CTOD, KIC, JIC and JR curve methods (where applicable).

Support with specimen selection, preparation routes and test planning aligned to standards and objectives.

Traceable results with practical interpretation to support engineering decisions and procurement needs.
