Abstract:
1. 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, the biaxial tensile testing machine comprising: 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 respectively rotatably connected to 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.
