Stress and Movement of Ultraviolet Curing Resin in Curing Process

概要

論文の詳細を見る
Stress and movement in the curing process of ultraviolet (UV) curing resin illuminated by UV rays were simultaneously measured to investigate the relationship between the residual stress and the shrinkage of the resin. The stress was measured by a digital photoelastic technique in the manner of phase stepping, and the movement was measured from the movement of segments of string mixed into the resin. Results indicated that the directions of principal stresses of the resin in the curing process are related, to some degree, with the movement of the resin.
