Abstract: front page image
(EN)Apparatus and method for indicating stress in an object (10) comprising viewing the temperature variation of part of the surface of the object as it is stressed. An infra-red detector (13) detects small changes of temperature and the stress may be applied by natural loading or by cyclic stressing imposed by a vibrator.
