    • n clamp An instrument of wood, metal, or other rigid material, used to hold anything, or to hold or fasten two or more things together by pressure so as to keep them in the same relative position. Specifically— In joinery: An instrument of wood or metal used for holding glued pieces of timber closely together until the glue hardens. A piece of wood fixed to another with a mortise and tenon, or groove and tongue, so that the fibers of the piece thus fixed cross those of the other and thereby prevent it from casting or warping.

    • n clamp In botany, in the mycelium of fungi, a nearly semicircular cellular protuberance, like a short branch, which springs from one cell of a filament close to a transverse wall, and is closely applied to the lateral wall of the adjoining cell. Each cell coalesces with the clamp, and thus an open passage is formed between the two cells. Also called clamp-cell.

In science:

Fracture occurred first within the clamping area for one sample (473, 7, B) because the sample slid of the clamp, causing the screw to bear the tension load.
Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
However, it is not clear how the ”loose” boundary conditions (compared to the traditional wedge clamps) affect the fracture outcome.
Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
When a crack initiates, the load distribution is the coupons changed suddenly and the clamps are likely to reorient themselves, which could lead to premature fracture.
Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
None of the data collected in the current study allow for checking whether the clamps accelerate the fracture process. A non contact strain measurement system provided a non invasive method to estimate strain in the coupon.
Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics
Finally, the strain measurement procedure is 2D only, and consequently any relative motion of one of the clamps towards or away from the camera was seen as a change in strain, and therefore the measured strain could be overestimated (and the Young’s modulus underestimated).
