Abstract
Effects of laser energy on fatigue crack growth (FCG) properties of 6061-T6 aluminum alloy subjected to multiple laser peening (LP) were investigated. LP experiments and typical FCG experiments were performed on the compact tension (CT) samples. In order to reveal the enhancement mechanism of laser energy on FCG properties through residual stress (RS), a numerical model of effective stress intensity factor (SIF) was established. The results showed that compressive RS induced by LP can effectively decrease FCG rate and increase FCG lives of CT samples. The experimental results and numerical analysis correlated with each other.
