Corrosion Damage Residual Strength Research of Shot Peening Aluminum Alloy
The pre-corrosion damage tests of LC4 aluminum alloy with the shot peening surface treatment and un-shot peening surface treatment are performed under different time levels. The residual strength has been studied by test after corrosion damage. An analysis procedure is developed using 3D reconstruction solid model and finite element analysis to predict residual strength, The relationship of static intensity and the corrosion damage are founded. An effective engineering technique for predicting residual strength of corroded structure is established on the base of this studying work.
