Abstract
Holography has been used to measure the deformation of a diesel-engine piston heated through a low temperature rise in order to confirm the finite-element modeling of an isoformic piston being developed by Wellworthy Ltd. Previous work relating to the study indicated that a body movement had occurred on the piston and one of the main features of the current study was to measure the absolute movement at diametrically opposite positions on the piston. A single holographic plate was used for this purpose and produced the required results which, when averaged, compare favorably with finite-element results.
