本文发展了一种方法，通过有限元分析，在很宽的时间，载荷和温度范围内的聚合物的载荷和温度依赖的力学行为的建模。该方法包括材料模型以及材料参数的确定以校准模型。作为该方法的一个特点，该模型是通过使用从短期实验产生的蠕变数据进行校准。该方法改进了塑料部件长期行为的模拟，并显著减少了实验工作量。最后通过实例零件的蠕变实验验证了仿真结果。
This paper develops a method for the modeling of the load and temperature-dependent mechanical behaviour of polymers over a wide time, load and temperature range by means of finite element analysis. The method includes a material model as well as the determination of material parameters to calibrate the model. As a special feature of this method the model is calibrated by using creep data generated from short term experiments. The procedure improves the simulation of the long term behaviour of plastic-compo nents and reduces the experimental effort significantly. The simulation results are finally validated by creep experiments performed on an example part.
