Analytical determination of the constitutive behavior from micro-pillar testing: Application to a tempered martensitic steel
- Laboratory for Nuclear Materials, Nuclear Energy and Safety Research Department, 5232 Villigen PSI (Switzerland)
Micro-compression experiments were carried out on micro-pillars, with nominal diameter of 10 μm and height 20 μm, and fabricated from a high-chromium tempered martensitic steels developed for nuclear applications. An analytical method was proposed to calculate the imposed compressive displacement on the pillar that allows determining the constitutive behavior up to about 5% of plastic strain. The experimental micro-compression curves were showed to be adequately modeled by the finite element simulations, which were used to validate the main assumption considered for the analytical model development.
