Paper Abstract

Electronic speckle pattern interferometry is applied to examine stress distributions on a fiberglass reinforced doweled joint with increasing load levels. The dowel is embedded in the reinforced wood and is loaded in compression. The observation of the in-plane deformations on reinforced wood specimens is obtained in real-time. A continuous monitoring of the specimen enables one to detect the development of stresses in the axial direction of load. The stress distributions around the hole of unreinforced and reinforced bolted joints are compared.
