Problems on comparing analytical and numerical estimations of stressed-deformed state of structure elements

Аннотация

A methodical approach to estimating the accuracy of the stressed-deformed state of structural elements has been presented that consists of the reverse analysis of errors in analytical and numerical solutions. The novelty of the approach lies in defining the problems of comparing analytical and numerical results jointly with the developed method for estimating the computational errors. The approach makes it possible to increase the validity of computation results according to the applied computation procedures, which makes it possible to increase the reliability and safety of technical objects.
