Development of Fracture Model for Laser Screw Welding
レーザースクリューウェルディングの破断モデルの開発
This paper describes development of the Laser Screw Welding (hereinafter LSW) fracture model and validation of the model with experimental results. It is an issue in vehicle development that fracture model of LSW which can be welded in short pitch and with large clearance allowance have not been developed with being strengthened safety requirements in recent years. Since unknown material is created by stirring various molten metals composing of plates in joining, LSW fractures in various modes. Therefore fracture model was estimated difficult to develop. A model was developed to simulate fracture mode bifurcations and was validated with experiment results.レーザスクリューウェルディング（以下，LSW）は，短ピッチ溶接などの利点があるが，衝突解析用破断モデルは開発されておらず，開発の課題であるが，多岐の破断形態が存在し予測は困難であると考えられた．そこで，LSWの破断予測モデルを開発した．開発したモデルは，実験と良く一致する事を確認した．
