| description | Thermolastic Stress Analysis (TSA) has been recently developed as a direct investigating
method for the study of the stress field around the crack tip of a cyclically loaded structure. The
advantage of using measurement techniques based on the thermoelastic effect lays in the fact that
stress intensity factors may be determined based on the effective stress distribution around the crack
tip rather than calculated from the crack length and amplitude of cyclic loads. This paper reports
results related to fatigue tests on Friction Stir Welded alluminium alloys sheets. Fatigue crack
propagation experiments were performed by employing single-edge notched specimens, in tensiontension
condition with R=0.1, up to failure. The application of TSA allowed the monitoring of crack
formation and growth in real time, providing the actual stress distribution around the crack tip for
the different technological parameters used in the welding process. Stress intensity factors were
determined based on the TSA data and compared to those calculated using an ABAQUS FE model. |
