✦ Synopsis
A statistical analysis is presented for steady creep bending in a beam, where the material parameters are random processes alon,g the neutral axis arising from ran&an $uctuationa in temperature and imperfection density. Analytical and numerical results are presented for the statistical properties of the norm&l stress and lateral velocity. It is found that whereas the normal stress shows very little ra&Juctuation th.e lateral velocity is highly random. The statistics of the lateral velocity generally show a sign&ant dependence on the nominal value of the creep power and on the position along the neutral axis.
