Abstract
This paper describes the application of the shadow moire´ method for direct measurement of the whole-field defor-
mation of a cantilever beam, made from natural fiber-posite (NRFC) material, under static loading and
comparison of the experimental results with those predicted using finite element analysis (FEA). The material properties
required in the FEA were obtained by calculating the mean of the property values determined from three-point bending
tests on several standard test specimens made from the material. The classical phase-shift technique was used in the
shadow moire´ method to increase the measurement resolution. parison shows the existence of a non-zero
gradient at the base of the cantilever in the measured deformation profiles probably due to the clamping conditions of
the cantilever. However, the difference in deformation at the free edge is only mm over a length of 160 mm.
