Designing and Testing a 3D-Printed Specimen for Combined Loading
Abstract
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.
