Abstract
A HIGH FREQUENCY METHOD FOR DETERMINING THE NON PROPAGATION THRESHOLD OF FATIGUE CRACKS IN WHICH A CYCLIC LOAD (32 32A) IS APPLIED TO AT LEAST ONE TEST PIECE COMPRISING IN A TEST AREA (10A) AN ELLIPTICAL HOLE (12) HAVING A NOTCH (14) AT ONE APEX AND HELD BETWEEN TWO RIGID MASSES (24 26) TWO RIGID PRESTRESSING PLATES (20 22) BEING DISPOSED ON EITHER SIDE OF SAID TEST PIECE AND BEING SECURED AT EACH OF THE TWO ENDS (20A 22A; 20B 22B) OF SAME TO THE TWO RIGID MASSES THE FREQUENCY OF THE CYCLIC LOAD (32 32A) BEING CHOSEN AS EQUAL TO THE NATURAL FREQUENCY OF THE TEST PIECE/MASSES/PRESTRESSING PLATES ASSEMBLY SO AS TO GENERATE A FATIGUE CRACK FROM THE NOTCH; THEN WHEN IT IS OBSERVED THAT THE CRACK HAS STOPPED PROPAGATING THE FINAL LENGTH OF THE CRACK IS RECORDED AND SAID NON PROPAGATION THRESHOLD ?K OF THE FATIGUE CRACK IS DETERMINED USING A TABLE THE CYCLIC LOAD BEING OBTAINED BY A VIBRATING ELECTRODYNAMIC POT INTEGRALLY ATTACHED BY MEANS OF RIGID POSTS TO A FRAME SUPPORTING THE TWO RIGID MASSES AND COMPRISING A PUSH ROD TO TRANSMIT SAID CYCLIC LOAD TO THE TEST PIECE/MASSES/PRESTRESSING PLATES ASSEMBLY.
