SU1359650A1 - Specimen for determining deformation properties of materials - Google Patents

Abstract

The invention approaches the samples for studying the physicomechanical properties of materials. According to the invention, the greater certainty of the information about the deformation of the specimen during its testing is. When fabricating sample 1, flexible fiber-optic fibers 2 are placed in the body of the sample. Some ends of the light guide pipe 2 are bundled and connected to a light source, while others are outputted amp & face 4 flush, 1 il. -2

Description

The invention relates to samples for studying the physicomechanical properties of materials.

The aim of the invention is to increase the reliability due to the long-term fixation of the coordinates of the tags for any kind of load.

The drawing shows schematically the proposed sample

Sample 1 to determine the deformative properties of the material has through cavities placed in volume and facing the opposite edges of the sample. In these cavities, along their entire length, flexible fiber optic fibers 2 are placed. One ends of the flexible optical fibers 2 are assembled in a beam 3 and are connected with a light source (not shown), and the other ends of the optical fibers 2 are brought to the edge 4 of the sample behind the subdisc and are connected with a recorder (not shown),

Sample 1 is made from a hardening material. To fabricate the sample, the flexible optical fibers 2 are evenly distributed over the mold mold for pouring and the solution is poured into the mold. After solidification, one of the faces 4 onto which each end faces the optical fibers5 of the fibers along with the ends of the optical fibers. .

The test specimen is manufactured as follows.

From the light source along flexible fiber light guides 2, assembled in bundle 3, rays of light output: o /: 1; t to face 4 and enter the recorder, where the initial position of the optical fibers is fixed. To sample 1, a force is applied according to a predetermined program and the change in the position of the ends of the flexible optical fibers 2 is recorded on the recorder, which determines the deformation of the sample.
