摘要： Described herein are examples of improved material (and/or universal) testing machines having a lower crossbeam that may be moved via a drive system of the material testing machine. In some examples, this may be accomplished via drive shafts with different threading in upper and lower portions, and/or independent drive systems for upper and lower crossbeams. The ability to dynamically adjust (e.g., raise) the lower crossbeam may allow an operator to interact with test samples at a more comfortable height, and reduce the need for an operator to repeatedly bend and/or kneel.

摘要： A high-temperature in-situ loaded computed tomography (CT) testing system based on a laboratory X-ray source and a method therefor are provided. A dynamic sealing device is adopted. A pull-up pressure rod and a pull-down pressure rod are allowed to rotate circumferentially and move axially. Meanwhile, a high-temperature furnace is fixed without rotating or moving, such that the high-temperature furnace is flat in an imaging direction to shorten an imaging distance and improve imaging quality. An independent tensile testing machine is utilized to achieve high-load loading. The in-situ measurement of internal deformation and damage information of a specimen under tensile or compressive load in a high-temperature environment is implemented. By taking advantage of the miniaturization design of the high-temperature device, the accuracy of the damage test using the laboratory X-ray source is increased. Tests and researches on the internal damage and failure behavior of the high-temperature materials can be conducted.

摘要： To measure the fatigue ageing of an electronic component in an electronic assembly subjected to mechanical excitations, a dynamic correspondence is established between kinematic measurements at certain points and mechanical stresses experienced at points that are critical as regard to the reliability of the electronic assembly. The critical points may be different from the measurement points. This correspondence is integrated into a monitoring device as a functionality that calculates the mechanical stresses, thereby providing an indicator of the cumulative fatigue damage. The invention is such that the monitoring device can be incorporated into the electronic assembly, preferably, the monitoring device is autonomous both as regard to processing the measurements and calculating the damage.
