Determination of Flow Stress Curves of Zirconium Alloy by Dynamic Micro-Tensile Test Using Strain Gauge Technique

Popis výsledku v původním jazyce

One of the main uses of zirconium alloys is in nuclear technology, such as cladding of fuel rods in nuclear reactors, especially water reactors. Due to increasing safety demand of nuclear reactors, crashworthiness has become more important and potential crash accidents are calculated using the Finite Elements Analysis. The present work is focused on the investigation of an experimental zirconium alloy under various strain rates at room temperature. As there is in many cases lack of zirconium alloys for testing, miniature specimens were used. This technique was called micro-tensile test. Further advantage of M-TT is short parallel length (less than 3 mm) and strain rates reachable by these sample with the combination of impact tester IM30T are up to 2500 s-1. Force during a test was measured by strain gauge and the piezo electric load cell. For precise strain measurement, pictures captured by the high-speed camera were evaluated by the ARAMIS system using the Digital Image Correlation method (DIC). Flow stress curves as precise input for FEM simulation determined by micro-tensile test are presented here.
