Abstract:This work considers the influence of loading rate on the Weibull stress parameters in the Beremin model for 20MnMoNi55 RPV steel using finite element modelling of compact tension specimen. For failure analysis of cleavage fracture at component level, the Beremin model is very useful. To implement the Beremin model, the model parameters needed to be calibrated for this particular material with experimental observation. In the first portion of this study, some fracture experiments are conducted at -100°C for fou… Show more
