TWI Industrial Member Report Summary 786/2004
Rick Leggatt, Geert Verhaeghe and Elizabeth Olden report on the Structural Distortion Prediction System (SDPS) developed by TWI. SDPS uses a sequential elastic finite element analysis of the assembly of the structure in which distortions are generated at the welds as each new part is added into the model.
This report describes the development and testing of TWI's Structural Distortion Prediction System for modelling the accumulation of distortion during the fabrication of an aluminium TIG welded structure. The project was carried out in collaboration with BAE SYSTEMS.
To develop and evaluate a sequential elastic finite element procedure known as the Structural Distortion Prediction System (SDPS), for the prediction of the accumulation of weld distortion during the fabrication of complex welded components.
