    摘要： A tensile strength testing machine comprises a frame assembly that defines a test zone. The frame assembly includes a frame member that has first and second opposed ends. The ends have inner sides that generally face one another across the test zone, and outer sides that are generally opposed to one another and the test zone. An arbor element is mounted for generally axial movement relative to the first end. The arbor element is slidably mounted in the first end. The arbor element projects inwardly into the test zone and outwardly from the outer side of the first end. The arbor element is adapted to being attached to a test specimen, which mounted in the test zone. A portion of the arbor element that projects outwardly from the outer side of the first end is generally surrounded by an array of jack bolts. The jack bolts are threadably mounted in a collar member that is substantially axially fixed relative to the arbor element. The jack bolts are positioned to bear generally against the outer side of the first end. Typically, at least a thrust collar, and, preferably, a load determining assembly are interposed between this outer side and the bearing ends of the jack bolts. Torquing down the jack bolts against the outer side of the first end places the arbor element in tension. This tensile load is applied to a test specimen mounted in the test zone, and the magnitude of the load is determined.

    摘要： A system for making extensional measurements on a sample includes an armature, a motor drive shaft, a moveable cylinder, and a fixed cylinder. The motor drive shaft is attached to the armature. The moveable cylinder is mounted on the armature. The sample is stretched between the moveable cylinder and fixed cylinder by the rotation of the moveable cylinder around the axis of the fixed cylinder and rotation of the moveable cylinder about its own axis. The resistance of the sample produces a torque on the moveable cylinder and the fixed cylinder. The torque is measured on the moveable cylinder or on a transducer shaft attached to the fixed cylinder. The system is adaptable to a commercial rotational rheometer.

    摘要： A device for gripping a specimen for applying to the same tensile or torsional strain includes two plates spaced from each other and a tubular spacer extended between the two plates and accommodating a specimen. The specimen is attached to the plates by respective nuts. One end of the specimen extended outwardly from the respective plate and nut is formed by a threaded pin, on which a pulling device for applying tensile stress onto the specimen, is set. The other end of the specimen has a square portion to which a tap wrench is applied, which, with the aid of two bolts positioned on one of the plates, applies torsional strains to the specimen.
