A glass strength evaluation apparatus includes a support unit, a plate disposed on the support unit and including a surface on which a glass article, which is a target to be tested, is disposed, a fixing jig disposed on the plate and a power unit lifting up or down the fixing jig in a vertical direction toward the surface of the plate. The fixing jig includes a body portion, which extends in the vertical direction and lower fixing bolts. A press-fitting member insertion opening is recessed from a bottom of the body portion to extend in an upward direction, lower fixing bolt insertion holes penetrate the body portion, from one side of the body portion, in a first horizontal direction intersecting the vertical direction, to be extended to the press-fitting insertion opening, and lower fixing bolts are coupled into the lower fixing bolt insertion holes.

A method for testing a sample for ball dent properties is provided. The method comprises disposing a sample on a stage of a testing apparatus and moving a trigger assembly that contains a tip having a radiused terminus toward the sample such that the terminus impacts the sample one or more times.

An environmental conditioning assembly for use in mechanical testing at scales of microns or less. The assembly includes an enclosure housing with an environmental cavity therein. A sample stage is positioned within the environmental cavity and includes an option sample heater. The enclosure housing includes a cavity perimeter clustered around the sample stage, and the enclosure housing isolates the environmental cavity and the sample stage from an environment exterior to the enclosure housing. In an example, an expansion and contraction linkage maintains a sample on the sample stage at a static elevation according to heating or cooling fluctuations within the environmental cavity. A testing instrument access port extends through the enclosure housing into the environmental cavity.

Surface measurement probe comprising: a hollow probe body extending along a longitudinal axis and comprising a proximal end adapted to be mounted to a test apparatus and a distal end; a retaining arrangement situated inside the probe body and extending along said longitudinal axis, the retaining arrangement being arranged to maintain the surface measurement probe in an assembled state; a probe tip supported at the distal end of the probe body and arranged to contact a sample; a bead situated inside the probe body and interposed between the probe tip and the retaining arrangement, the bead comprising a thermally-insulating material.

A multiple degree of freedom sample stage or testing assembly including a multiple degree of freedom sample stage. The multiple degree of freedom sample stage includes a plurality of stages including linear, and one or more of rotation or tilt stages configured to position a sample in a plurality of orientations for access or observation by multiple instruments in a clustered volume that confines movement of the multiple degree of freedom sample stage. The multiple degree of freedom sample stage includes one or more clamping assemblies to statically hold the sample in place throughout observation and with the application of force to the sample, for instance by a mechanical testing instrument. Further, the multiple degree of freedom sample stage includes one or more cross roller bearing assemblies that substantially eliminate mechanical tolerance between elements of one or more stages in directions orthogonal to a moving axis of the respective stages.

A film structure puncture testing tool for testing the resistance to puncturing of a film structure for a product package and a method for analyzing film structures resistance to puncturing.

A method for determining the curing behavior of an adhesive- or sealant bead, the adhesive- or sealant bead being applied to a workpiece, places multiple test bodies on the adhesive- or sealant bead at different, pre-defined placement times, and deformations of the adhesive- or sealant bead, caused by the test bodies, are measured at a pre-defined end time.

A heating system for use in mechanical testing at scales of microns or less includes a stage heater. The stage heater having a stage plane, and a stage heating element distributed across the stage plane. Two or more support mounts are on opposed sides of the stage plane. A first bridge extends from the stage plane to a first mount of the two or more support mounts, and a second bridge extends from the stage plane to a second mount of the two or more support mounts. The first and second bridges provide a plurality of supports between the stage plane and two or more support mounts to accordingly support the stage plane. In another example, the heating system includes a probe heater configured to heat a probe as part of mechanical testing.
