Estimation on Aluminum Alloy Residual Stress Considering the Influence of Hole-Drilling Diameter

Abstract:

A method of hole-drilling to estimate residual stress of welding joint of 2219-T87 aluminum alloy is proposed based on numerical simulation and measurement test. The influence of drilling-hole diameter to welding residual stress is first analyzed by numerical simulation, and the optimal diameter is obtained as 4.0 mm. In accordance with the diameter, carry out a test on measuring welding residual stress. And the maximum residual stress is calculated as 123.2 MPa.
