The Safety Study on Corrosion Damage of LC4 Aluminum Alloys by Finite Element Method

Abstract:

. The corrosion damage data are obtained through the pre-corrosion accelerated experiment which is performed under three different time levels: 24h, 48h and 72h. Based on the corrosion damage data, a three-dimension (3D) solid model is created by CAD. An analysis procedure is developed using CAD and finite element analysis to predict stresses and residual strength due to corroded pits. The residual strength results of specimens are obtained from the model based on the corrosion damage data. The simulation results are compared with the true testing static intensity results and the method is proved that it is reliable and effective in engineering.
