讲座内容：

Improvement of the predictive accuracy for defect formation, such as fracture and springback, using finite element analysis (FEA) is key to realizing trial-and-error-less manufacturing. In metal forming processes, materials are subjected to various multiaxial stress states. Therefore, the accuracy of the material models used in FEA should be accessed by using the material testing methods that accurately reproduce such complex stress states. This lecture reviews the advanced material testing methods for sheet and tubular metals. Special attention is given to the anisotropic plastic deformation behavior of industrial materials and to the validation of the material models for large plastic strain ranges. In addition, the effects of material models on the improvement of the predictive accuracy of FEA simulations are discussed.
