Abstract

Aluminum are frequently used as light weight structure in various nautical design. One of them is the ship structure design where sever environment of saline water influences the damage of the structure and one among them is pitting. In this paper, an experimental verification of strength and impact of corrosion effect on Al-6063 – T6 aluminum was presented. The specimens were exposed to saline water for various duration like 500hrs, 750hrs and 1000 hrs and tensile strength and yield strength was examined. The low velocity impact like 1J, 2J and 3J were used to make the damage on the specimens. Further, specimen’s residual strength was examined. Also, the strength reduction was verified through a mathematical formulation developed on the basis of residual strength model. The environmental exposed specimen’s data are compared with without exposed specimens and influence of environments are scaled. The theoretical results are almost matched with experimental results only with a difference of 2% approximately All observed results are presented in tables and figures for compared.
