Damage influence in deep drawing and stretch forming (A06)

在子项目A06中，矩形杯形件通过拉深(AP1)和拉伸成形(AP2)成形。根据损伤状态和循环性能来表征这些形成的部件。在此基础上，在AP3中设计了拉深和拉伸成形工艺，以提高这些部件的性能。用铁素体不锈钢(AP4)验证了该方法对其他材料的可转换性。在AP5中，形成了在A04、A08和B06生产的板材，以测试所开发的方法对循环性能的影响。

In subproject A06 rectangular cups are formed by deep-drawing (AP1) and stretch-forming (AP2). These formed components are characterized with respect to the damage state and the cyclic performance. On this basis, in AP3 a deep-drawing and a stretch-forming process are designed to increase the performance of these components. The transferability of the methods to other materials is verified using a ferritic stainless steel (AP4). In AP5 the sheets produced in A04, A08, and B06 are formed to test the impact of the developed methods on the cyclic performance.
