THE EXTENSION OF A FATIGUE CRACK IN A MODEL STEEL DECK PLATE UNDER CYCLIC LOADING
THE MODEL DECK WAS SUBJECTED TO LOCAL CYCLIC VARIATIONS OF LOADING, PRODUCING BI-AXIAL BENDING. THE GROWTH OF THE FATIGUE CRACK CAUSED BY THIS LOADING WAS MEASURED BY AN INDIRECT METHOD OF COMBINING CONTINUOUS OBSERVATION OF STRAIN WITH A THEORETICAL PREDICTION OF THE RELATION BETWEEN THAT STRAIN AND THE CRACK LENGTH. IT WAS FOUND THAT A LINEAR RELATION EXISTED BETWEEN THE LENGTH OF THE CRACK AND THE NUMBER OF CYCLES OF LOAD AFTER ITS INITIATION, AND THE RATE OF GROWTH OF THE CRACK FOR VARIOUS APPLIED LOADS WAS PREDICTED. /AUTHOR/
