A Simplified Calculation of the Stress Fields in the Tube Wall Based on a Nonlinear Model of Magnetoelastic Effect

摘要

A simplified scheme for evaluation of the stress change proceeding from the distribution of magnetic scattered fields on the tube surface in the stress-strain conditions is proposed. The scheme is based on an original nonlinear model of magnetoelastic effect and makes it possible to find a correlation between the the scatterd field integrals (along the coordinates on the tube surface) and stress changes without using any preliminary information about the shape of stress distribution.
