Investigation of fuel mechanical properties by micro-indentation
An innovative tool was developed to perform instrumented micro-indentation tests using a Vickers indenter, from the ambient temperature up to 1200°C. At present, a series of indentation experiments were carried out on stainless steel, fused silica and un-irradiated UO2, including experiments with either force or displacement control. Calculations were done to determine the Vickers Hardness and Young's modulus.
In order to interpret in depth the experimental results, a finite element model was developed. The computational results are in a good agreement with the experimental load/displacement curves.
