Mesoscopic simulation of selective beam melting (B04)

介观尺度允许研究由光束、粉末和熔体之间复杂的相互作用产生的现象。一方面，迄今为止仅限于金属的数值模拟工具将通过半结晶热塑性塑料模型进行扩展，以使其适用于聚合物。另一方面，将实现三维晶粒生长模型，以预测金属部件的局部织构。数值实验将进行，以支持实验项目在发展创新的加工策略。

The mesoscopic scale allows the investigation of phenomena resulting from the complex interplay between beam, powder and melt. On the one hand, the numerical simulation tool, which has been restricted on metals so far, will be extended by a model for semi-crystalline thermoplastics in order to make it applicable on polymers. On the other hand, a 3D grain growth model will be implemented in order to predict the local texture of metallic components. Numerical experiments will be per-formed in order to support the experimental projects in developing innovative processing strategies.
