Provided are a tension-torsion loading tooling, and a tension-torsion loading test system thereof, belonging to the technical field of material testing. The tension-torsion loading tooling includes a connector, a clamping head, and a connecting rod assembly. The connecting rod assembly includes four horizontal connecting rods, and four inclined connecting rods, the four horizontal connecting rods are sequentially hinged from end to end to form a parallelogram structure, and each of four diagonal corners of the parallelogram structure is hinged with one end of each of the four inclined connecting rods. The other ends of two inclined connecting rods on the diagonal corners are hinged with the connector, and the other ends of the other two inclined connecting rods are hinged with the clamping head. The tension-torsion loading test system includes a tensile testing machine, and a tension-torsion loading tooling.

A tensile test fixture for securing a polymeric foam test specimen is described. The tensile test fixture comprises a first gripping member including a first support surface, a first side wall and a second side wall. The first support surface, first side wall, and the second side wall form a first specimen end receiver that is receptive of a first end of the test specimen. A second gripping member includes a second support surface, a first side wall portion and a second side wall portion. The second support surface, first side wall portion, and the second side wall portion form a second specimen end receiver that is receptive of the second end of the test specimen. Neither the first specimen end receiver nor the second specimen end receiver exerts a compressive force on corresponding ones of the first end and the second end of the test specimen.
