| Summary: | My Projek Sarjana Muda (PSM) is regarding a study and analyze problem
those related the fracture mechanic on the spot welded joint. This project enables me
to collect all the relevant information about spot welded concept and the application
of spot welded. This study presents the fracture of the spot weld, sheets thickness and
stresses on the the spot-weld joints to predict the maximum stress and location of the
weakest spot-welds at the specimen of spot welded joint. A simple model was used
to illustrate the technique of spot-weld stress analysis. Finite element model and
analysis were carried out utilizing the finite element analysis commercial codes.
MSC nastran patran analysis was carried out to predict the stress state along the weld
direction. It can be seen from the results that the predicted life greatly influence the
sheet thickness, nugget diameter and loading conditions of the model. Acquired
results were shown the predicted life for the nugget and the two sheets around the
circumference of the spot-weld at which angle the worst damage occurs. The spotwelding
fracture analysis techniques are awfully essential for automotive structure
design. |
