There are well-established procedures for assessing the significance of defects in welded structures in a number of countries, however, there are no clear guidelines for such assessments under dynamic loading. In principle, standard procedures can be applied for any rate of loading, but there is little or no experience as to how to allow for the effects of dynamic loading on load magnitude or rate of loading in such assessments. In this project, work has been carried out jointly by UMIST and TWI to investigate effects of dynamic loading on structural integrity assessments for fracture.
