A support jig for use with a testing machine applying loads, the support jig includes a frame and a pair of spaced apart supports joined to the frame to provide an alignment axis. Each support is configured to releasably hold a test specimen holder on the alignment axis in a fixed spatial relationship with ends of the test specimen holders mountable to the test machine facing in opposite directions. A test specimen support is located between the holders holds the test specimen on the alignment axis so that the holders can be attached to the test specimen. The support jig allows the holders to be easily and correctly attached to the test specimen so as to maintain alignment of the holders and the test specimen on the alignment axis. The support jig also maintains the fixed spatial relationship of the holders and test specimen while the holders are mounted to the test machine.

Disclosed is a material testing system that includes an output shaft configured to be moved by operation of a motor, the output shaft coupleable to a test specimen such that movement of the output shaft imparts a mechanical force on the test specimen. The material testing system includes a haptic feedback system configured to provide an operator of the material testing system haptic feedback related to a position or state of the output shaft relative to the test specimen during setup. Methods of testing using haptic feedback are also disclosed.

A fixing jig is provided, including a supporting base, a fixing plate, and a fixing component. The supporting base includes a first upper surface. The fixing plate is disposed on the supporting base. A side of the fixing plate is pivotally connected to the supporting base and includes a second upper surface, a bottom surface, and via a hole. The fixing component presses the fixing plate on the second upper surface. The fixing jig can fix an object pending testing and allows one flexible electric circuit board of the object pending testing to be exposed outside of the fixing jig, so that when performing a pull force test, this can allow an angle between two flexible electric circuit boards to be 90 degrees, thereby improving accuracy of an experimental result.

An assembly for shock testing a specimen, the assembly including first and second opposing brackets and opposing lower and upper caps. The opposing brackets include lower and upper angled surfaces. The lower cap includes lower angled surfaces configured to engage the lower angled surfaces of the left and right brackets. The upper cap includes upper angled surfaces configured to engage the upper angled surfaces of the left and right brackets. The first and second brackets are configured to be drawn toward each other via fasteners, thereby wedging the lower and upper caps toward each other against the specimen.

The invention relates to a fastening assembly (3) for fastening a test device holder (5) to a force measuring apparatus (1), having a test device holder (5) and a slide part (7) which can be or is arranged on a force measurement tower (9) of the force measuring apparatus (1) in such a way that the slide part can move in the vertical direction of the force measurement tower (9). The test device holder (5) has at least one position defining element (11), and the slide part (7) has at least one counter position defining element (13). The position defining element (11) and the counter position defining element (13) are designed to fix the position of the test device holder (5) relative to the slide part (7) in at least one direction, selected from the vertical direction of the force measurement tower (9) and a direction perpendicular to the vertical direction, and at the same time to allow rotation of the test device holder (5) relative to the slide part (7) about an axis of rotation (D) defined by the position defining element (11) and/or the counter position defining element (13). The test device holder (5) has a first angle adjustment device (15) and the slide part (7) has a second angle adjustment device (17), which are designed to adjust and preferably to fix the angle of the test device holder (5) relative to the slide part (7) about the axis of rotation (D). The test device holder (5) has at least one fixing element (19) and the slide part (7) has at least one counter fixing element (21). The fixing element (19) and the counter fixing element (21) are designed to fix the test device holder (5) on the slide part (7).

Provided is a material testing machine capable of giving an appropriate testing force to a testing piece. The material testing machine performs a three-point bending test on a testing piece and includes a support mechanism that supports the testing piece, an indenter that is connected to an ultrasonic oscillator and gives ultrasonic vibration to the testing piece by abutting against the testing piece, and a load mechanism that presses the indenter to the testing piece supported by the support mechanism. The support mechanism includes: a spherical seat that has a lower member equipped with a spherical-surface-shaped concave portion or convex portion, and an upper member equipped with a spherical-surface-shaped concave portion or convex portion having a shape corresponding to the concave portion or convex portion in the lower member; a holding portion; and a first movable member.

A test coupon (1) for an ISO-standard-conforming test method for testing a material hardness of gearwheels. The test coupon (1) is designed as a two-piece test coupon (1) including a casing body (2) and a test body (3). The test coupon (1) being tested by an ISO-standard-conforming test method for determining a material hardness of the gearwheels.

An assembly for shock testing a specimen, the assembly including first and second opposing brackets and opposing lower and upper caps. The opposing brackets include lower and upper angled surfaces. The lower cap includes lower angled surfaces configured to engage the lower angled surfaces of the left and right brackets. The upper cap includes upper angled surfaces configured to engage the upper angled surfaces of the left and right brackets. The first and second brackets are configured to be drawn toward each other via fasteners, thereby wedging the lower and upper caps toward each other against the specimen.

The device for preparing sheet specimens comprises a base (1) for placing on it a sheet specimen (2) and a cutting punch (3) for cutting sheared cracks or sharp notches in said sheet specimen (2). Preferably, said cutting punch (3) comprises a beveled lower end (31) and/or a central vertical groove (32). Permits the cracks to be formed cutting directly the sheet, and not by cyclic loading, so that the preparation of the sheet specimen takes a reduced time in comparison with the conventional devices.

The invention pertains to performing bonding strength testing between a test material and a container. A sample preparation device to make a test sample was disclosed. This device included a container with an insert on each end. The inserts have a portion that protrudes into the container. When test material is added to the sample preparation device, a groove was formed in test sample. These grooves reduce the amount of boundary effects that are present during testing.

A system and method for performing bond strength testing was also disclosed. In this system, a test sample was formed using the sample preparation device. This is placed upon a support and a half-spherical force applier is placed on top of the test sample. A press is used to apply force to the force applier and indirectly to the test sample.
