| Özet |
| Mechanical properties and formability of TWIP900 steel, which is a new material for automotive industry, are investigated. TWIP steels have a good combination of high strength and high formability. Therefore, they are very attractive for the automotive industry. The energy absorption capability of the steel during collisions is a significant advantage. The biggest disadvantage of this steel is the relatively high springback of stamped parts. Tensile and springback behaviors of the material are investigated and compared with DP600 steel which is widely used in automotive industry. Besides, yield surfaces and forming limit diagrams for both materials are modelled and compared with each other. Results indicate that the use of TWIP steel will contribute weight reduction significantly, but the springback issue needs to be resolved. In finite element modelling of TWIP steel, it is seen that the Swift model gives more accurate results than the Backofen and Holloman models. |
