Mechanical properties of workpiece materials are important factors affecting the formability and the accuracy of products in metal forming processes. In the present study, an numerical simulations of the simple spinning process of metal plates were performed by using a 3D elasto-plastic finite element method, and the first attempts to clarify the influences of workpiece properties upon the spinning formability were carried out. The stress-strain relation of the workpiece material was found to affect the final dimensions of the workpiece in spinning process. This result is owing to the different strain distribution based on the different mechanical properties of the workpiece. Meanwhile, the initial thickness anisotropy of the material showed minor influences upon the strain distribution of the final shape of the workpiece.
