Results of fracture mechanics analyses of the ederer cranes in the device assembly

PDF Version Also Available for Download.

Description

Fracture mechanics analyses were conducted on three critical locations on the lower flange of the load-beam of the Ederer 5 ton and 4 ton cranes in the D.A.F. Facility. Based on these results, it appears that: 1. Propagation of a 5 mm long flaw, previously undetected by non-destructive examination (NDE), to a length sufficient to cause structural failure of either flange, should not occur in at least 100 times the postulated operating scenarios for each crane; 2. Should each crane undergo annual inspection, any surface flaw with a length greater that 20 mm should be removed and repaired by qualified ... continued below
