Abstract
The results are presented to create a facility for studying dynamic tension of structural materials by using the Split Hopkinson Bar Method (SHB method). The explosive method of loading and a cylindrical corner-rounding sample are used in a facility. A sample has threads at both end faces and it fastened in rods by the help of threads. The results of test experiments are presented in the facility for studying dynamic tension of the aluminum alloy AMg-6 at strain rates of 1160-1450 s-1. The diagrams of dynamic tension σ-ε were built. The data on peculiarities of deformation AMg-6 were gained.
Highlights
To develop constructions, the experimental data are required concerning the behavior of materials under the different temperature-velocity loading conditions
Samples of aluminum alloy AMg-6 were made of a rod in as-delivered condition. 4 tests were implemented at dynamic tension; the strain rate έ in tests was 1160-1450 s-1
A process of deformation and damage was recorded via a rapid video camera, a velocity of video filming amounted to 4 104 frames per second
Summary
The experimental data are required concerning the behavior of materials under the different temperature-velocity loading conditions. One of the types of the experimental data relates to the results of dynamic tension of materials with strain rates of 102-103 s-1. The data on dynamic tension are gained in many cases by using a Split Hopkinson Bar method (SHB method) [1,2,3,4,5,6,7,8].
