Volume 6, Issue 1 , Summer and Autumn 2016, , Pages 39-50


  Warpage and shrinkage control are important factors in proving the quality of thin-wall parts in injection modeling process. In the present paper, grey relational analysis was used in order to optimize these two parameters in manufacturing plastic bush of articulated garden tractor. The material used ...  Read More

3. Dissimilar friction stir lap welding of Al-Mg to CuZn34: Application of grey relational analysis for optimizing process parameters

Saman Khalilpourazary; Reza Abdi Behnagh; Ramezanali Mahdavinejad; Nasib Payam

Volume 4, Issue 1 , Summer and Autumn 2014, , Pages 81-88


  This study focused on the optimization of Al—Mg to CuZn34 friction stir lap welding (FSLW) process for optimal combination of rotational and traverse speeds in order to yield favorable fracture load using Grey relational analysis (GRA). First, the degree of freedom was calculated for the system. ...  Read More
