The present disclosure relates to a specimen testing machine which includes: a specimen test unit comprising: a pair of gripper parts configured to respectively hold opposite ends of a specimen, a gripper fixing part configured to fix at least any one of the pair of gripper parts, and a specimen driving part configured to move the specimen in a longitudinal direction of the specimen; and a guide plate unit including: a guide plate that is configured to be moved along with a folding direction of the specimen, and to be folded at a center portion thereof, and a second driving part comprising a second fixing part configured to fix opposite ends of the guide plate, and configured to move the specimen in the longitudinal direction of the specimen.

A tribological testing simulator includes a base having a pair of catchers that clamp onto a specimen, a punch that is drawn through the specimen, and a plurality of sensors that take measurements of respective regions of the specimen. The sensors measure their respective regions of the specimen as it is drawn from an un-deformed state to a deformed state, and facilitate conducting a tensile strip friction test. In some embodiments, the catchers have flat inserts that facilitate conducting a strip stretch or draw test simultaneously with a tensile strip friction test. In other embodiments, the catchers include drawbead inserts that facilitate conducting a drawbead friction test simultaneously with a tensile strip friction test.

A tension testing apparatus and system is disclosed in which the tension testing apparatus includes a first box including a first outer plate and a first inner plate, a second box including a second outer plate and a second inner plate, and a test sample holding system coupled to the first inner plate and the second inner plate. The first outer plate and the first inner plate may be coupled together by at least two rods. The second outer plate and the second inner plate may be coupled together by at least two other rods. The test sample holding system may be configured to hold a test sample. The at least two rods of the first box may be configured to pass through the second inner plate. The at least two rods of the second box may be configured to pass through the first inner plate.

A portable flexure fixture including a fixture housing, a translatable plug, a load ring, and a support ring. The fixture housing includes a first end opposite a second end, a plug receiving opening extending into the first end and a test opening extending into the second end. The support ring is disposed in the fixture housing. The translatable plug is insertable into the plug receiving opening of the fixture housing and is translatable in both a sample engaging direction and a sample releasing direction. Further, the load ring is coupled to the translatable plug and is positioned at a sample facing end of the translatable plug such that translation of the translatable plug in the sample engaging direction translates the load ring in the sample engaging direction and translation of the translatable plug in the sample releasing direction translates the load ring in the sample releasing direction.

The present invention includes a load frame test device using a plurality of levers about a common pivot point for applying combinations of tensile loading and bending on test articles at magnitudes seen in offshore applications.

A device for performing a mechanical four-point bending test on a test piece and to a method for using one such device. The device comprises: a) structure for holding a first end of the test piece (27; 127; 28; 128) and structure for holding a second end of the test piece (30, 31); b) traction wire (25) and converting structure (16, 116) for converting a translational movement of said traction means into a rotational movement; c) conversion structure (26; 27; 126; 127) for converting said rotational movement into bending deformation of the test piece. Said conversion structure comprises at least one first Cardan joint (26; 126), connected to the structure for holding the first end of the test piece.

An example material testing apparatus includes: guide means; sample holding means for holding a sample; force means for applying force to the sample; a crosshead arranged to support at least a portion of one or both of the sample holding means and the force means, wherein the crosshead is moveable about the guide means; automated clamping means configured to apply a releasable clamping force between the guide means and the crosshead to secure the crosshead at a location with respect to the guide means, and a controller configured to control the automated clamping means to apply the clamping force between the guide means and the crosshead.

A test piece includes a tensile testing part and load applying pieces that are respectively connected to sides of the tensile testing part. Grooves are formed on bottom surfaces of the load applying pieces. Grooves are formed on upper surfaces of the load applying pieces. These grooves respectively partition the upper and lower surfaces of the tensile testing part and the load applying pieces.
