The mechanical properties of biological tissues is important for different areas of research. However, due to the size of the tissue, only small tissue samples can be obtained. For this reason, this study focused on the development of a small tissue sample geometry for tensile testing. A sample geometry was designed based on ISO standard 527 and a cutting die was made by additive manufacturing machine. The performance of the die was assessed by testing with poultry tissue. Finally, a finite element model has been analyzed to study the stress distribution of the gage area of the specimen.
