Title: Shot peening intensity influence on the fatigue behaviour of aluminium alloy ASTM 2011

Abstract: 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.
