Abstract. A strategy for the selection of optimal smoothing parameter for hybrid experimental-numerical photoelastic experiment is proposed in this paper. This is not a straightforward procedure for photoelastic analysis since conventional finite element techniques are based on the approximation of nodal displacements, not stresses. Although the displacements are continuous at inter-element boundaries, the calculated stresses are discontinuous due to the operation of differentiation.
