Exposures get more complex, methods are manifold. Often constructs made of plastics can be determined statically as well. For this, conventional analytical methods were used as well as 3D-fem-analysis.
To keep the effort in a convenient limit, to be aware of essences and to achieve the maximum requires experience and established attainment. The duties and responsibilities are interdisciplinary for the most part. Here knowledge of the range of construction analysis, of specific characteristics of plastics and of manufacturing methods is questioned in equal measure.
