摘要：
The deformation responses of AZ31B magnesium alloy under complex forming process are investigated experimentally through using the specially designed loading device consists of two metal blocks with two symmetrical bevelled ends. Based on digital image correlation analysis, the deformation process of specimen is clarified and the typical deformation modes are proposed. Results show that compression dominate the deformation response of specimen with smaller loading angle, while shear deformation becomes the major mode when the loading angle large enough. And an empirical formula is established for quantitative description the relationship between strain path and loading angle.
