Abstract Scratch simulation of polymeric materials has been a challenging task. It requires a material constitutive model that is capable of representing the complicated material response at large strains, and also a modelling method that can comprehensively resolve several physics, i.e., tribology, material deformation and damage, indenter statics and dynamics. This paper discussed the use of two finite element simulation approaches: (i) Abaqus/Explicit Arbitrary Lagrangian-Eulerian (ALE) adaptive meshing and (ii) the Coupled Eulerian-Lagrangian (CEL), in modelling scratches of talc-filled polypropylene using an elastic-plastic with isotropic hardening material model and a hyperelastic-viscoelastic model. The models were evaluated with scratch experiments and a very good agreement between the simulations and experiments was found. Various technical challenges in modelling scratch of polymeric materials were discussed and solved during the development of both successful methods and their merits and drawbacks were also discussed in detail.

聚丙烯板上划痕的有限元模拟

摘要 聚合物材料的划痕模拟一直是一项具有挑战性的任务。它需要能够表示大应变下复杂材料响应的材料本构模型，以及能够综合解决摩擦学、材料变形与损伤、压头静力学和动力学等多个物理场的建模方法。本文讨论了两种有限元模拟方法的使用：(i) Abaqus/显式任意拉格朗日-欧拉 (ALE) 自适应网格划分和 (ii) 耦合欧拉-拉格朗日 (CEL)，使用滑石粉填充聚丙烯的划痕建模具有各向同性硬化材料模型和超弹性粘弹性模型的弹塑性。这些模型通过划痕实验进行了评估，发现模拟和实验之间非常吻合。
