Comparative analysis of forming limit diagram of Al 5052-H32 and Al 6063 T5

Abstract

Formability of a material is found to be one of the important characteristic of a sheet metal to know the variation of the major and minor strain of a sheet metal, using this value one can predict the forming limit diagram of sheet metal, forming limit diagram gives the behavior of sheet metals under various loads and also helps in the prediction of breakage or necking of the material under specific load and velocity of the punch. Current study is mainly focused on obtaining the forming limit diagram of two different aluminium alloys like Al-5052 H32 and Al-6063 T5 using numerical analysis software PAMSTAMP and the results obtained are validated by conducting experiments, there is a good agreement of results between the experimental and numerical values. The forming limit diagram of the mentioned alloys helps in manufacturing of automobile and electric vehicle parts.
