Shot peening intensity influence on the fatigue behaviour of aluminium alloy ASTM 2011
vol. 51 (2013), no. 4, pp. 263 - 268

The aim of this study is to determine the possibilities of mass reduction of dynamically loaded aluminium alloy structures. Specimens were prepared from heat-hardened aluminium alloy ASTM 2011. In order to improve the fatigue behaviour the specimens were shot-peened. The experiment was planned using the software package ❞Design Expert❞. The research results were used to develop mathematical function among: lifetime, the level of alternating symmetric stress and Almen intensity. These results indicate the possibility of mass reduction of structural elements from ASTM 2011, according to the selected parameters.

Key words
shot peening, aluminium precipitation, Almen intensity, fatigue testing
