微珠用于拉深钣金件，以增加零件的刚度。因此，减少钣金厚度，从而减轻重量可以达到。珠子的类型和位置的样式指南是存在的，它们经常被应用。然而，通过数值优化可以实现更高的刚度效果。该优化算法考虑了拉深和冲压两步制造过程。在这两个制造步骤的成形性是一个限制因素。采用广义成形极限概念（GFLC）考虑非线性应变路径，在模拟中确定可接受的几何形状。其中，将在数值和实验测试中选择具有较高刚度效应的有效几何形状。这些将被整合到优化算法中。
Beads are used in deep drawn sheet metal parts for increasing the part stiffness. Thus, reductions of sheet metal thickness and consequently weight reduction can be reached. Style guides for types and positions of beads exist, which are often applied. However, higher stiffness effects can be realized using numeric optimization. The optimization algorithm considers the two-stepped manufacturing process consisting of deep drawing and bead stamping. The formability in both manufacturing steps represents a limiting factor. Considering nonlinear strain paths using generalized forming limit concept (GFLC), acceptable geometries will be determined in simulation. Among them, the efficient geometry which has higher stiffness effects will be selected in numerical and experimental tests. These will be integrated in the optimization algorithm.
