The late F.P.J. Rimrott has published during his scientific life more than 200 refereed articles and conference papers. Various papers among them were devoted to the creep and plasticity analysis in metallic thin-walled structural elements mostly published in the period from 1958 till 1964. With regard to this early period below we discuss finite element solutions for moderately thick plates under creep-damage conditions based on shell and solid type finite elements. The results illustrate the time-dependent stress redistributions in the edge zones. We show that the transverse normal and shear stresses may have a significant influence on the damage evolution and must be considered in numerical lifetime estimations.
