Analysis of Size Effect in High-Cycle Fatigue for EN AW-6063
Any changes in specimen size in relation to the reference dimensions involve scaling inaccuracies resulting in the variances in strength testing (monotonic, fatigue) results. It is referred to as a size effect. The size effect is described using a cross-sectional coefficient determined for various specimen sizes and test types. The analysed material is aluminium alloy EN AW-6063 T6 with a cross-sectional area of 28, 7 and 3.5 mm2.
