Abstract

In order to solve critical process parameters characterize aluminum grating is proposed to optimize the impact of stress calculation values are based on a nano-indentation experiment - Method strain relationship parameters. By establishing numerical approximation model to fit the experimental data of training, and the experimental data for numerical optimization. Experimental results show that: the method to calculate the yield strength aluminum material property parameters, namely strain hardening exponent, and obtained more satisfactory aluminum material properties parameter elastic modulus and yield strength relationship by comparing the value of the deviation can be found in the obvious effectiveness of this approach, but also proved a reliable orthogonal experiment. The research process parameters characterize the relationship between the aluminum grating characterization and constitutive model provides a reference and basis for, and also provide a basis for the development of intelligent raster scored.
