The effect of material and surface properties of polypropylene (PP) on scratch behavior were discussed by parametric studies using finite element analysis (FEA). Two different loading conditions were examined. It is found that Poisson's ratio has a negligible effect on scratch performance. Increasing yield stress and reducing coefficient of adhesive friction are important ways to positively affect the scratch performance of polymer. However, increasing the Young's modulus does not necessarily improve scratch performance. FEA, elasto-plastic, parametric study, scratch resistance, polypropylene.
