This paper describes the miniature specimen test technique as employed on irradiated materials for the study of mechanical behavior of in-service engineering components/structure. A rectangular miniature specimen of size 10 mm × 2.5 mm × 0.50 mm is considered as a test sample. Small punch test technique is employed to perform the experiments on miniature sample. The sample acts like a fixed beam during testing. Two different structural steels (Die steel D3 and Chromium steel H11) are used for the miniature specimen preparation. The resulted experimental data are suitably correlated for the evaluation of mechanical characteristics i.e. yield strength, and fracture toughness. The evaluated values of yield strength and fracture toughness using proposed correlation are compared with the values obtained from standard tests. The ABAQUS computer code is employed for the FEM simulation of the small punch test on rectangular specimen. The experimental and FEM load displacement curves are compared and found in good agreement.
