抄録

In the previous reports, one of the authors showed that a long specimen's in-plane strain geodetically estimated from the final shape after laser forming has sufficient agreement with the in-plane strain measured from a distance change of landmarks.<br>For short specimens, these two type in-plane strains are not compatible because of the in-plane strain parallel to laser heating line.<br>To form bowl shape thin plate by laser forming, accurate in-plane strain should be introduced into the plate. So, both parallel and perpendicular in-plane strains should be presented accurately for objects in various size and shape.<br>In this report, effects of both specimen length and initial curvature on in-plane strains in two directions, parallel and perpendicular, are investigated experimentally.
