Abstract
Real structures inevitably contain small material flaws due to e.g. welding. Traditional design methods consider these defects only implicitly using safety factors and yield easily to excessive conservatism. More accurate design methodology can be based on direct application of fracture mechanics.

This paper presents several computer tools developed at the Technical Research Centre of Finland VTT for the assessment of flawed structures. They include flexible tools for assessing deliberate structure-loading-crack configurations with the finite element method - most often used for failure analysis - and effective tools for rapid structural integrity assessments even during the structural design phase.
