Fixed Value Residual Stress Test Block And Manufacturing And Preservation Method Thereof

摘要

A fixed value residual stress test block, comprising a main body (1) and two welded blocks (2); the main body (1) and the welded blocks (2) are all rectangular metal blocks; the welded blocks (2) are welded onto the two opposite side surfaces of the main body (1); the main body (1) is deformed under the upper and lower pressures and generates residual stress. The fixed value residual stress test block has a simple structure.
