| Abstract: | The formability of tailor welded blanks is different from that of single material blanks.Studying on the formability of TWBs makes benefit to improve the forming process.As an effective and practical material property test method,tensile test was applied to study it.Base material and tailor welded blanks test specimens were designed for tensile testing and the test was carried out.The strength and plastic properties of different TWBs were obtained and the results were discussed.The results indicate that the tensile strength of TWBs is between higher strength base material and lower one,but the formability is lower than any base material.At the same time,the weld line location in the TWBs has a significant impact on the formability. |
