Abstract

The vibration behaviour of local ship structures is highly influenced by residual stresses and predeformations. Measurements have shown that differences of up to 50% in natural frequencies due to welding stresses are possible (Hanke [1]). Uncertainties of this magnitude contain a high risk regarding the estimation of the vibration behaviour during operation of the ship. This implies an economic threat in case of failure to fulfil contracts and therefore an improvement of the prediction of local vibration behaviour is needed.
