Failure investigations

Fatigue of materials is the main cause of failures. Material defects, high stress concentrations or unforeseen loads can be involved. To make clear the cause of failure, it is necessary to assess the effect of possible material defects in combination with the structural design and the load conditions.

I make impartial failure investigations that can form the basis of regulation of claims for compensation in insurance disputes. I cooperate with other experts and various laboratories for e.g. metallographic analyses and strength testing.

To investigate and solve problems with fatigue in welded structures is my special field.
