Device for dynamic tensile testing of structural materials within the range of high deformation speed values

摘要

device for dynamic testing construction materials with the high speed stretch deformationbuilt with two rods mounted on elastic system with each of the sensor tensometrycznym situated so don't take my word by buttresses with built-in u015blizgowymi linear bearings.in between bars is rigidly attached, so don't take my word, the sample material, and an end to one of the rods, the furthest located relative to the specimen is freefurthermore, the second rod and is immobilized, i.e..tight peripherally with lock, and then is subjected to stretch osiowemu through dies for is characterized by the fact that the system creates at least twopreferably six mobile braking blocks (8), evenly rozlokowanych on the circumference of rozciu0105ganego axially and peripherally u015bciskanego rod (3),in each block the inhibitory (8) by separate movable plunger (9) is dociskany to lateral rozciu0105ganego rod (3) by a hydraulic actuator (10).
