| Abstract Scope |
The determination of plastic deformation properties of materials under high speed loading is a challenge. The system ringing in a conventional servo-hydraulic tensile machine deteriorates the quality of force measurement. A precise determination of the plasticity and damage is thus difficult.
In this work, the system ringing effect of the entire test system incl. machine, sample etc. were analyzed. We found out that the system ringing is location and geometry dependent. Inspired by the principle of the SHPB a new type of tensile sample has been developed.
In a certain restricted area of this new sample, the tensile forces can be measured without any ringing effect. The plastic deformation and damage behavior can be determined using this type of specimen for a wide range of strain rate of 0.0001 - 1000 /s. To explain the functionality of the sample and the sample design, a physical model has been developed. |
