... stress r rw prdr r 2 2 is positive (or is increased, or more compressive) for both hot and cold injections; however, the thermal-induced radial stress r r T w Trdr r 2 is positive for hot injection but becomes negative (or is decreased, or more tensile) for cold injection. Therefore, the induced...
