Measuring fracture resistance behaviour of tungsten using chevron-notched micro-cantilevers
- Abstract:
-
The fracture properties of tungsten-tantalum alloy (W-1%Ta), one of the candidate material for the plasma facing components in proposed fusion reactor design, were investigated using microscale chevron-notched cantilever bending tests at both ambient and high temperature (700 °C) conditions.
Finite element analysis (FEA) were used to optimise the crack stability of the chevron notch design and obtain the geometry-dependent stress-intensity factors (SIFs) and stiffness vs. crack len...
