Identification of temperature-dependent parameters for an elastic-plastic-damage material model of 3D-printed PETG

Popis výsledku v původním jazyce

The presented paper focuses on identifying temperature-dependent parameters for a newly designed material model of 3D-printed PETG (polyethylene terephthalate glycol). An uniaxial elastic–plastic material model with damage and different properties in tension and compression was developed to describe this material’s non-linear behaviour. The monotonic and cyclic tests were carried out in tension and compression at several temperatures. The specimens were printed using FDM (fused deposition modelling) technology on the printer from Prusa Research. The principal material parameters such as Young’s modulus, yield stress and ultimate tensile stress were derived directly from the force–displacement diagrams obtained experimentally. Other necessary material characteristics were identified using numerical simulations combining the finite element method and parametric optimization. The model was implemented for the software Abaqus using subroutine UMAT and the optimization was performed using software Isight.
