Abstract
The volume shrinkage ratio and the residual stress that occurs at the curing shrinkage of acrylic resin were measured. The volume shrinkage ratio was measured with the laser displacement detector system and the dilatometer. The volume shrinkage ratio of acrylic resin was about 16%. Most of the volume shrinkage resulted in about 12 minutes after the mixture. The residual stress in interface of adhesive layer was calculated by measuring the residual strain of adherend. The influence of the residual stress on the adhesive strength must be considered.
