The results obtained from the simulation are compared with those derived from analytical approach that assumes a plane mean surface. These will be useful for designing and constructing displacement and deformation measurement systems using digital correlation technique. <br /> <br />Full Text: <a class="file" href="/PLP/index.php/letters/article/view/4-20/218" target="_parent">PDF</a> <br /> <strong><br />References</strong> <br /> <ol> <li>P.
