Finite element modeling of indentation and adhesive wear in sliding of carbon fiber reinforced thermoplastic polymer against metallic counterpart

In this work, adhesive wear in uni-directional (UD) reinforced carbon thermoplastic Polyetherimide (PEI) composite laminate caused by the sliding of a metallic counterpart is analyzed. The study is based on the finite element method (FEM) in various in-plane directions of sliding relative to fibers....

Description
Summary:In this work, adhesive wear in uni-directional (UD) reinforced carbon thermoplastic Polyetherimide (PEI) composite laminate caused by the sliding of a metallic counterpart is analyzed. The study is based on the finite element method (FEM) in various in-plane directions of sliding relative to fibers. The damage and failure mechanisms induced by the adhesive wear are predicted with 3D Hashin's theory and Puck's theory. These failure theories were implemented in ABAQUS via UMAT in implicit environment. The damage mechanisms predicted by the FEM model showed a better correspondence with the observed damage modes in the wear experiments of fiber reinforced polymers (FRPs). Furthermore, specific failure exposure factors were also compared with the specific wear rates determined experimentally in a qualitative manner. •3D Puck’s theory has been used to investigate the damages that are induced during the sliding of a metallic counterpart against the fiber reinforced polymers (FRPs) specimen.•The 3D damage topography of the damage zone was obtained by element deletion when the damage exposure factors exceeded one.•Parametric study was also carried out to investigate the effects of the coefficient of friction and normal force on the damage.•The specific damage exposure factors computed based on the Puck’s theory were compared with the experimental specific wear rates in a qualitative manner.
