In this work the „brocade” method is presented and used to determine mechanical properties of biological materials. Young modulus and Poisson ratio have been determined for frozen fababean. Microscopy images of randomly deposited markers on samples surface have been transfered to computer memory. Then changes in marker positions were analyzed. The method is precise and can be applied also for wet materials. Moreover the method is not affected by any side effects present in the sample close to attachments. Results obtained for fresh, frozen and dried fababean have been compared. Young modulus and Poisson ratio were very close for frozen and fresh fababean samples.
