Abstract
The flow and stress of ultraviolet (UV) curable resin dung curing were simultaneously measured and their relationship was investigated. The flow is observed as particle trajectory patterns obtained using a particle tracking velocimetry technique, and stress as isochromatics and principal-stress directions obtained using a photoelastic technique, respectively. The specimens consist of glass plates, acrylic plates and UV curable resin in liquid form with acrylic powder. The specimens are illuminated with UV rays downwards from the upper side of the specimens, and the visual and photoelastic images of the resin in curing process are captured at a constant time interval using a digital and CCD cameras, respectively. Results indicated that to discuss in detail the relationship between the stress and flow, the thermal stress generated in the glass plates constituting the specimens must be deleted.
