<p>A biaxial tensile testing machine performing a tensile test of a test piece by stretching the test piece in four directions along two axes perpendicular to each other includes: first and second turntables which are disposed so as to be parallel to each other and relatively rotatable about a rotary axis along the planer direction thereof; first to fourth link mechanisms which are provided at 90° intervals in the circumferential direction about the rotary axis so that one ends of respective members of a pair of members are rotatably connected to each other, and the other ends of respective members of the pair of members are attached across the first and second turntables; and first to fourth test piece holding units which are respectively attached to the first to fourth link mechanisms and hold the test piece.</p> |
