In subproject B01, the mechanical material behaviour is modelled in addition to the thermal behaviour in order to be able to take into account the internal stresses arising in the cooling process of the plastic melt in the optimization. With this basis, more complex materials such as fibre-reinforced plastics and hindered shrinkage can be modelled, whose influence on moulding distortion is less dependent on temperature distribution and cooling rate. In addition, the approximation of the tempering channel layout is extended to drilled channels and further modification options for setting the optimum heat balance are investigated and added to the design methodology.

在子项目B01中，除了热行为之外，还对材料的机械行为进行建模，以便能够在优化过程中考虑塑料熔体冷却过程中产生的内应力。在此基础上，可以模拟更复杂的材料，如纤维增强塑料和受阻收缩，其对成型变形的影响较少依赖于温度分布和冷却速度。此外，回火通道布局的近似扩展到钻孔通道，并进一步修改选项设置最佳的热平衡进行了研究，并添加到设计方法。
