Modelling of Laser Directed Energy Deposition considering the resulting properties of hybrid porous structures (A05)

A05的目标是L-DED过程的模拟环境，该环境结合了不同的规模级别，以整体地描述制造过程期间和之后的低质量组件。微观水平的热流体结构模拟指定了有效的热输入和应用层的形状。特征级模型计算热致残余应力。在构件层面，大型次元构件可以通过空间和时间可变的特性（如形状、残余应力、温度和孔隙度）有效地描述。

The goal of A05 is a simulation environment of the L-DED process that combines different scale levels to holistically describe a HyPo-component during and after the manufacturing process. A micro level thermo-fluid structure simulation specifies the effective heat input and the shape of the applied layer. A feature level model calculates the thermo-induced residual stresses. On component level, large HyPo-components are efficiently described by spatially and temporally variable properties, e.g. shape, residual stresses, temperature and porosity.
