| Abstract | ||||
| The authors have applied fatigue crack bending test of thin sheets for the determination of the crack propagation rate in AU4 G1-T3 aluminium alloy and in type 316 austenitic stainless steel. In the first stage, the authorshave tested the Paris' law and shown its insufficienties, then they have interpreted the results with ELBER'sTheory of crack closure and have measured the crack opening by means of a strain gauge installed near the crack tip. In addition, the authors have explained the retardation phenomenon due to a single overload in Al. alloy. | ||||
