Experiments, hyperelastic modeling and finite element simulation of 3D‐printed thermoplastic polyurethane

Abstract: A combined experimental and numerical investigation on the mechanical behavior of 3D‐printed thermoplastic polyurethane is presented. In particular, the behavior under monotonic loading until rupture is considered. For this purpose, tensile test specimens are analyzed, which were produced by conventional injection molding and by an extrusion‐based additive manufacturing process. The additively manufactured test specimens have notched surfaces that influence the failure behavior due to stress and strain concentrations. For the numerical analysis, a finite element modeling approach is presented with which the experiments are simulated. It is shown that the tensile curves can be simulated using a hyperelastic material model and that first indicators can be found that enable a prediction of failure under monotonic tensile loading.
