I need simulation of rotary friction welding on Abaqus for my masters project work. Mechanism of friction welding: Friction welding is a solid state process for joining materials together with the help of the frictional heat generated from the movement of one component relative to another one under a force. Rotary friction welding is the most popular method. Generally, one material is held stationary while the other material is rotated with the application of a compressive axial force. Thermal energy (heat) and plastic deformation (abrasion) is generated in the rotation and friction phases and chemical inter diffusion occurs primarily in the forging phase. Due to the complexity of this process, the kinetics of interface formation during RFW remain widely unknown. Stages in Rotary Friction Welding: . FW occurs in five stages. First stage is “frictioning stage” which starts when two parts are in contact and then, rubbing starts at the weld [login to view URL] speed is held constant at this stage, while a friction force is applied to the parts for appropriate rubbing to initiate the development of thermal energy. During this stage, the torque reaches from zero to its peak value. Axial shortening is very little at this stage. The second stage starts after the initial peak torque is reached, and continues until the equilibrium stage. Axial shortening starts mainly during this stage due to gradual softening. The applied axial load causes the softened material to flow radially outwards to form an upset collar. Next stage is the “equilibrium stage”, during which resistive torque remains nearly constant. “Braking stage” follows the “equilibrium stage”. When the WI is heated and a predetermined amount of axial shortening takes place at frictioning pressure value, electric motor is turned off and braking is applied. As soon as the speed of the rotation starts to decrease, peak terminal torque value is obtained. When the relative movement between the two parts ceases, it then falls and reaches to a zero value. Last stage is “upset stage”, which starts before the braking stage is finished, by increasing the frictioning force to an upset force; it lasts until a predetermined time or reduction in length (i.e. burn-off length) is completed. Material: Both the WP of Mild Steel. Material Model: Johnson Cook Material Model Parameters: 1 Friction pressure :2–4 bar 2 Friction time: 2–6 s 3 Forging time :3–10 s 4 Forging pressure: 2–6 bar 5 Rotational speed : 800–1,600 rpm
