Fatigue cracking is one of the primary damage mechanisms of metallic components. It occurs as a progressive damage due to dynamic stresses in areas with a variety of physical defects.

Verify your loads, and dynamic toughness up front of fatigue failures.

Stress measurements and evaluations
Our main goal is to get ahead of the factors which leads to fatigue failures. One of the essential parameters for a crack-growth to occur is the dynamic tension represented in the specimen. A proper quantification of this parameter is an impotent input to lifetime calculations.
Aker Solutions has wide experience within dynamic measurements. We have skilled personnel on a wide range of measuring equipment - both handheld and multi-channel data loggers with simultaneous logging as an option. We are especially skilled for assignment regarding geometries, stress concentrations and material properties.
