NUMERICAL STUDY OF GEOMETRICAL EFFECTS IN LONGITUDINAL NON-LOAD-CARRYING FILLET WELDED JOINTS. FINAL CONTRACT REPORT

Finite element calculations, using a 3-D elastic program, have been carried out to define the value of mk (factor by which k for welded joint exceeds k for a cracked plate with the same size and shape of crack) for joints of several dimensions and hence to enable their fatigue strengths to be calculated. An attempt has been made, for a limited range of geometries, to define the relative influence of the various geometrical dimensions on the strength of the joint. Further work would be required in order to obtain sufficient data to be able to express the results in non-dimensional (and therefore generally applicable) form. Further work is also required to check the theoretical predictions against existing test data and to obtain additional data relating to some of the variables. (TRRL)
