摘要：IN THIS PAPER A NON-DESTRUCTIVE INVESTIGATION METHOD IS PROPOSED TO DETERMINE THE MECHANICAL CHARACTERISTICS OF THE ORTHOTROPIC MATERIAL, IN THIS CASE THE MASSIVE WOOD. DURING THE RESEARCH, DIFFERENT TYPES OF SPECIMENS WERE ANALYZED IN THE FORM OF A DISC SHAPE WITH 80 [MM] DIAMETER. THE DISC WAS ROTATED SO THAT THE FIBERS ORIENTATION CLOSES IN 150 LINE ANGLES WITH THE VERTICAL AXE DIRECTION. THE IMAGE REGISTRATION TECHNIQUE WAS APPLIED AS INVESTIGATION METHOD, IN WHICH THE FREE-FORM ALGORITHM WAS APPLIED AS INTERPOLATION STRATEGY. THE SOFTWARE OFFERS THE POSSIBILITY TO DETERMINE PLANE STATE DEFORMATION WITHOUT THE SOLID MOVEMENTS.
