The High Flux Test Module (HFTM) in International Fusion Material Irradiation Facility (IFMIF-DONES) has a purpose to irradiate material specimens to a very high fluence (DEMO relevant ones) in a very few years. The current design of HFTM is described in , given that DONES will involve external labs for testing, the sub-miniaturization of the currently defined HFTM matrix is needed to invoke cost/time-reduced transportation and handling of the test samples. With this respect, all types of tests could be sub-divided into two types: (i) design data and (ii) supportive/screening data. This task will contribute to the development and validation of the sub-miniaturized samples to generate supportive data to enable pre-selection of materials as well as to guide the test regimes for standardized samples needed to generate design data. This action includes the development of simplified sub-size geometry to perform bending tests on Tungsten, Steels and CuCrZr from which the extracted data will be linked to the tensile properties as well as could be used to identify the transition temperature range for standardized fracture toughness tests. The implementation of the technical work is supported by FEM analysis, which includes the development of a computational algorithm to extract tensile properties of materials from sub-miniaturized three-point bending (SUB-3PB) tests with ANSYS software.
