A BEND METHOD FOR MEASURING FATIGUE CRACK PROPAGATION IN THICK MATERIALS.

Abstract

A fatigue machine is described for making crack propagation experiments in bending, on specimens up to half inch thick. The test specimen is small and of simple shape to minimise machining time and cost. The machine can be readily adapted to make tests at high temperatures and to run at different frequencies. For two aluminium alloys comparison experiments on specimens cut from the same sheet of material gave good agreement for tests made in tension or in bending. (Author)
