A sample gauge length and length after fracture measuring device includes a worktable, a first sliding table support and a second sliding table support, a control and length display, a spiral micrometer head, a scriber, a sample, etc. The reading device using the spiral micrometer head to directly measure the gauge length and the length after fracture has a detection accuracy of 0.01 mm, which is superior to the requirement of 0.05 mm in GB/T228 Metallic Materials Tensile Testing at Ambient Temperature.

A rock damage mechanics test system for high temperature and high pressure deep earth environment includes an MTS triaxial test machine and a control system connected therewith. The MTS triaxial test machine is composed of a rigid frame, a high temperature and high pressure triaxial chamber, and a triaxial chamber base. The control system includes a workstation for data processing and a manual controller for controlling the workstation and a master controller. The system improves mounting and dismounting efficiency of an MTS triaxial force sensor, enhances reliability of lifting and solves the problem of aligning holes during the force sensor mounting process, thus improving the mounting efficiency.

A peel testing device designed to test the resistance to peeling of test pieces each formed from a support and from a reinforcement glued to this support, and comprising a frame with a face roller and at least one guide roller, a traction machine configured to peel the reinforcement from the surface of the support in a peeling direction tangential to the face roller and a sensor for measuring the force exerted by the traction machine during peeling, the device also comprising a fastening cable connected, on the one hand, to the traction machine and on the other hand to the face roller with which it forms a pulley system and the face roller which has a greater diameter than that of the guide roller comprises a mounting element for holding the reinforcement fixedly there.

Novel markers that can be attached physically to a tensile specimen with a center guide to allow for measuring correct strain, as well as a binder that fixes and holds a pin guide to its location on the specimen during the test.

A tool comprising a plurality of wear indicators is provided. The tool may be made from a rapid prototyping process. The tool may be used in an abrasive processing operation. The tool may comprise one or more control elements, (e.g., control geometries, part interfaces, fixture interfaces and/or the like). These control elements may comprise indicators of tool wear. The indicators may be inspected physically (e.g., by touch) and/or visually.

A mechanical testing system having a frame, and a stage for holding a sample. An arm for pressing a tool against a surface of the sample. A primary actuator is connected to the frame and applies a primary force and drives the tool relative to the sample, thereby causing the frame to flex. A displacement sensor measures a displacement value comprised of two components, the first component including a distance traveled by the probe into the sample as the primary force is applied, and the second component including a measure of a degree of flex of the frame as the primary force is applied. A compensating actuator is connected to the frame and applies a compensating force that reduces the second component of the displacement value.

A method and an apparatus for detecting bending stiffness and a method for testing a display panel. The method for detecting bending stiffness includes: arranging an object to be tested on a reference surface to make a stationary portion and a rotating portion of the object to be tested attached to the reference surface, the stationary portion and the rotating portion being connected to each other; driving the rotating portion to bend from the reference surface toward the stationary portion, and acquiring a rotation angle between the rotating portion and the reference surface; acquiring a bending force received by the rotating portion when the rotating portion is bent from the reference surface toward the stationary portion; and determining bending stiffness of the object to be tested on the basis of the bending force and the rotation angle.

A hardness tester includes a measurer (CPU) measuring a value for a material characteristic of a sample in conjunction with formation of an indentation, an acquirer (CPU) acquiring measurement data associated with the value for the material characteristic of the sample measured by the measurer, and a determiner (CPU) accumulating a predetermined value for the material characteristic based on the measurement data acquired by the acquirer and determining a time to replace the indenter based on the accumulated value for the material characteristic.
