Resumo: This work presents a new approach to achieve the third order spatial derivatives of out-of-plane displacements field using a full field technique. The Michelson Shearography technique is used to obtain the first order derivatives. The second and third orders are computed using multiple exposed Shearography technique with digital superposed method. An experimental procedure is proposed for the measurement of the first order derivatives. A steel clamped plate loaded with a uniform pressure was tested for internal stresses calculation. A good agreement between the experimental results and analytical solution is presented.
