Notes:
The ultrasonic welding process of thermoplastic composite with different shapes of energydirector (ED) was simulated using finite element model. The results show that the highest temperaturezone locates at the tip for the semicircular and triangular ones, and locates at the middle height for thetrapezoid one. But it does not locate at the body of ED for the rectangular one. Energy director withdifferent shapes lead to the temperature rising rate at different order of amplitude. The weldingamplitude has same influence on the four shapes of ED. The temperature distributing profiles ofsemicircular, triangular and trapezoid ED keep constant from the initial welding time to that when thehighest temperature on joints arrives the temperature of glass transformation (Tg), but the profile forrectangular ED changes greatly
