Ho Chi Minh City Vietnam . Received May 17 2005 Revised August 15 2005 Abstract. The author considers an elastic strip of thickness represented in Cartesian coordinates by The strip is clamped at the bottom the upper side is in contact with a rigid stamp and is assumed to be free from shear and the normal stress . 0 on away from the bottom of the stamp. The purpose of this note is to determine the stress field in the elastic strip given the normal displacement and the lateral displacement under the stamp.
