Evaluation of influencing variables :
- material properties
- manufacturing processes: edge or protective layers, effect of residual stresses, composite materials, material composites
- structural design: component size, component shape, notches
- operational stresses: single- and multi-stage, component-like, transient, influence of multiaxiality, temperature, temperature change, weathering, corrosion; wear of metals, ceramics, plastics, composites and material composites
