Abstract
For the desired energy and resource conservation in future lightweight concepts, detachable connections such as aluminium connections play an important role. Great potential in terms of reliability has been identified for aluminium bolts produced by equal-channel angular pressing (ECAP). Nevertheless, the mechanical properties of such bolts, required for a safe design of components, has not been adequately studied so far, especially not for dynamic load situations. Within this work, first results of fatigue tests of aluminium bolts of dimension M10x50 of aluminium alloy EN-AW 6082 and ECAP optimized EN-AW 6082 are presented and compared with properties of conventional bolts of the EN-AW 6056 series. Based on these findings, causes of failure are described and presented in the format of a fault tree analysis.
