    • Abstract
  • The finite element model of different material mechanics treated by ultrasonic impact was established based on finite element software ABAQUS to explore their influences on welding stress and strain. The effects of elastic modulus, poisson's ratio and the initial yield strength of material on stress and strain were discussed, respectively. The results show that elastic modulus, poisson ratio and initial yield strength of material can affect the stress and strain. With the increase of elastic modulus, compressive stress of x direction can increases, while the equivalent plastic strain decreases. With the increase of poisson ratio, stress of x direction and equivalent plastic strain will increase, but the effect of the poisson ratio on the equivalent plastic strain is greater than that on x direction stress. With the increase of the initial yield strength, stress of x direction will increase, and the equivalent plastic strain decreases significantly.
