ABSTRACT
This paper presents elastooptical method for assessment of carrot root displacement under impact load. The main purpose of this study involved an analysis of cross-section model of carrot root performance. The investigation by means of the polariscope was conducted. In each phase under load, a characteristic isochromatic pattern distribution was determined. Tested model was made of the polyurethane elastomer which provided mechanical properties similar to biological features. Stress distribution in selected cross-sections as well as in two mutually perpendicular σx and σy directions was also determined. On basis of the results a cross-section model of carrot root has been performed.
