摘要

采用基于内聚区模型的有限元方法研究了纳米碳化硅颗粒(SiCp)增强铝基复合材料的微加工过程。采用分层多尺度模拟方法,从分子动力学模拟的应力-位移曲线中得到内聚区模型的参数。该模型考虑了碳化硅颗粒分布的随机性以及碳化硅颗粒与基体之间的结合界面。从切屑形貌、应力分布、切削温度和切削力等方面分析了切削力学特性。模拟结果表明,纳米SiCp的随机分布导致刀具与增强颗粒之间的相互作用不均匀。这种变形力学导致应力分布不均匀,切削力变化不规则。

Finite element simulation of the micromachining of nanosized-silicon-carbide-particle reinforced composite materials based on the cohesive zone model

A finite element method based on the cohesive zone model was used to study the micromachining process of nanosized silicon-carbide-particle (SiCp) reinforced aluminum matrix composites. As a hierarchical multiscale simulation method, the parameters for the cohesive zone model were obtained from the stress-displacement curves of the molecular dynamics simulation. The model considers the random properties of the silicon-carbide-particle distribution and the interface of bonding between the silicon carbide particles and the matrix. The machining mechanics was analyzed according to the chip morphology, stress distribution, cutting temperature, and cutting force. The simulation results revealed that the random distribution of nanosized SiCp causes non-uniform interaction between the tool and the reinforcement particles. This deformation mechanics leads to inhomogeneous stress distribution and irregular cutting force variation.
