METHOD FOR CREATING A META-MODEL FOR CALCULATING NOTCH STRESSES

摘要

In order to enable the calculation of notch stresses for a plurality of cross sections to be evaluated with reduced computational effort and reduced error susceptibility, a method for creating a meta model for calculating notch stresses for a cross section to be evaluated (Q 1.. proposed at least one weld (S) with a notch having components (B 1 ... m), wherein the evaluated cross section (Q 1 ... m) of each component (B 1 ... m) by a specific combination of N the cross-section (Q 1 ... m) to be evaluated is defined as the geometric parameters (P 1 ... N) characterizing the component (B 1 ... m) and their concrete values,wherein the following method steps are carried out:- Definition of an N-dimensional parameter space;- Creating a discrete number of cross-sectional models;Calculation of notch stress information for each cross-sectional model as a function value of a support point determined by the respective cross-sectional model;- Creating the meta-model in the form of an N-dimensional, preferably continuous, function, wherein the function values of the meta-model are approximated at the support points to the function values of the support points themselves.
