| Description
| - Paper deals with ductile damage parameters identification of material used for nuclear parts construction under quasi-static and dynamic loading condition in the temperature range 20-300 °C. Based on the experience and extensive literature survey the design of suitable test specimen was performed [1,2,3]. Final design of each test specimen was evaluated by the numerical simulation. The damage process itself is evaluated based on the equivalent plastic strain which represents accumulated plastic deformation in the material at the moment of the fracture. The calibration experiment is performed with as constant as possible values of triaxiality, Lode parameter, temperature and strain rate. The evaluation of mentioned parameters is performed on samples using classical means as extensometer and load cell in combination with high speed camera, video-extensometer and DIC (Digital Image Correlation). The loading of the special type of samples is performed using custom - made testing devices as BUTTERFLY , NAKAZIMA or BIAXIAL (under development) The calibration of the plastic response curve and identification of the damage initiation criteria is based on the optimization script algorithm developed on CVUT [4,5,6,7]. The output will be ductile damage parameters which could be directly used in ABAQUS environment for numerical solution of the nuclear parts. Further subroutines will be elaborated to include more sophisticated damage models.
