... probability applied for determination of the Weibull parameters using two q1, q2, and q3 parameters of GTN model types of SE(B) specimens at -80°C. The GTN parameters were W specimen s width determined from fracture data of 1TC(T) specimen at the room temperature. The prediction analyses of the flat plate...

... if a continuum damage model can simulate a four-points beading test on a ferritic pipe (A508 type). In this paper, the theoretical background is presented. Then, based on finite elements analyses, the GTN model damage parameters are defined by simulating laboratory tests on Notched Tensile specimens and Compact...
