Abstract

Continuum damage mechanics (CDM) based on finite element analysis was performed to predict the mechanical behavior of a 3D-printed curvilinear continuous carbon fiber reinforced thermoplastic (c-CFRTP). Elastoplastic properties of the 3D-printed c-CFRTP including damage initiation, evolution, and propagation were identified using monotonic and cyclic tensile tests for three specimens, i.e. [(±45)₂]_S, [(0/90)₂]_S, and [(±67.5)₂]_S. Then, S-shaped curvilinear c-CFRTP was 3D-printed and tested in monotonic tensile loading. The non-linear mechanical behavior of an S-shaped curvilinear c-CFRTP due to tensile loading was well predicted by means of finite element analysis using the constructed CDM-based material model.
