Failure prediction is of essential importance for everything built in today’s world. Components are fabricated lighter and more specific in shape in order to fulfil their
purpose. For reasons both of safety and stability, an exact prediction of the potential failure location and path is required. Recently new failure criteria were found
for uniaxial loading. Since loadings are very seldom uniaxial but combined, a specimen for combined bending and torsion was designed and tested in a uniaxial
testing machine. The specimens were 3D printed with polycarbonate and various modifications such as holes and different loading cases. The purpose of this is to
verify if the failure criteria are applicable for combined loading as well. Comparing the experimental failure stress, location and path with the prediction made by
the criteria the results are very similar. This allows the assumption that the failure criteria are also valid for combined loading.Helut-Schmidt-Universität, Universität der Bundeswehr Hamburg Fakultät für Maschinenbau Professur für Mechatronik Holstenhofweg 85 22043 Hamburg, GermanGerman Armed ForcesApproved for public release; distribution is unlimited
