Abstract: This study investigates transverse stress relaxation in welded steel plates. Two different methods of stress measurement were used; strain gages and critically refracted longitudinal (LCR) waves. ...

Abstract: Nondestructive evaluation (NDE) techniques offer time-efficient methods for determining properties as well as characterizing defects in materials and structures. Application of these NDE techniques ...

Abstract: A pressure vessel has been constructed for demonstrating the LCR ultrasonic technique for indicating changes in wall and weld stress. A special contoured LCR probe was designed and constructed, ...

Abstract: Most of the methods for determining residual stresses inside metallic solids are destructive, which is undesirable. The ultrasonic technique provides a useful nondestructive tool in the evaluation ...

Abstract: Cross-linked polyethylene is widely used in the manufacturing of rotationally molded tanks for the agriculture, petroleum, and chemical industries. These tanks are exposed to a number of environmental ...
