Abstract
The utility model discloses a kind of membraneous material tensile test specimen, comprise dumbbell shape film test piece and end clamping device, wherein end clamping device comprises the two panels grip block consistent with dumbbell shape film test piece end shape, two panels grip block is bonding with the end of dumbbell shape film test piece respectively, and two ends of dumbbell shape film test piece are provided with end clamping device; The utility model can directly mate with traditional drawing machine standard dumbbell fixture, needn't special adaptive fixture, there is not any impact to the material property of test specimen equidistance line marking section.
Description
Technical field
The utility model belongs to mechanics of materials studying technological domain, particularly a kind of membraneous material tensile test specimen.
Background technology
Along with the development of modern science and technology, various membraneous material is widely used.The mechanical property research of membraneous material is a current large focus.Tension test is the most basic test of research material mechanical property, carries out stretching research to membraneous material, and what first need to solve is exactly the clamping problem of membraneous material.
What usual cupping machine was equipped with is wedge shape stretching clamp, its ultimate principle is by the threaded screw rod on alignment jig, spacing between adjusting wedge, adapt to different plates specimen thickness, but this type of fixture all exists minimum grip thickness when designing, be less than the material of this thickness and the softer material of general quality cannot be tested by clamping.
After the general bonding contiguous block of strip type film test piece, film distance between upper and lower side contiguous block is specimen equidistance line marking, this gauge length size need be given when bonding, and this just causes actual gauge length and is easy to be subject to the impact in artificial bonding engineering, there is certain error with theoretical gauge length; On the other hand, there is potential impact in the solidification of bonded adhesives and the mechanical property of performance on membraneous material and contiguous block abutting edge, causes the final material mechanical performance deviation to some extent obtained.
Therefore, need design one badly targetedly, and test itself is not produced to the membraneous material tensile test specimen of any impact.
Summary of the invention
The purpose of this utility model is that providing a kind of can directly mate with traditional drawing machine standard dumbbell fixture, needn't special adaptive fixture, the material property of test specimen equidistance line marking section is not existed to the membraneous material tensile test specimen of any impact.
The technical solution realizing the utility model object is:
A kind of membraneous material tensile test specimen, comprise dumbbell shape film test piece and end clamping device, wherein end clamping device comprises the two panels grip block consistent with dumbbell shape film test piece end shape, two panels grip block is bonding with the end of dumbbell shape film test piece respectively, and two ends of dumbbell shape film test piece are provided with end clamping device.
The utility model compared with prior art, its remarkable advantage:
(1) the utility model does original tensile test specimen and simply improves and can obtain, and structure is simple, easy to process.
(2) clamping device of the present utility model is arranged on the end of test specimen, and holding area is comparatively large, at utmost can ensure the gripping performance of test specimen.
(3) the utility model clipping operation is convenient, only needs to carry out a certain amount of manually bonding, just carries out the clamping of film test piece by standard dumbbell fixture, needn't special adaptive fixture.
(4) the utility model avoids tradition and clamps the impact on material mechanical performance that brings, the effective guarantee confidence level of test findings.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the utility model membraneous material tensile test specimen.
Fig. 2 is the use exploded perspective view of the utility model membraneous material tensile test specimen.
