More Information
Summary:PURPOSE: A residual stress measurement system under varying load and a measurement method thereof are provided to measure the residual stress of a test piece by applying load to a test piece and keeping the load. CONSTITUTION: A residual stress measurement system under varying load includes a load applying unit(100) and measures the residual stress of a test piece by load. The load applying unit includes a frame(110), a fixing unit(120) installed to the frame to fix two ends of a test piece, and a load applying unit(140) connected to the fixing unit to apply load to the test piece quantitatively and by stages and to maintain the applied load.
