The work described here is part of a larger experimental and theoretical program directed at obtaining a better understanding of the mechanics of flame bending. A capability for predicting the transient behavior of a line heated plate during heating and cooling is presented. Material properties are temperature dependent. Elastic-plastic stress-strain relations are used. Material unloading from the plastic range is treated. Deformations of a plate are predicted at various times during heating and cooling and compared with experimental results. The analysis is also carried out for consecutive heating and cooling cycles.

Simplified Analysis

The paper presents an analysis of the deformations and stresses in the rolling contact of solids of revolution. The simplified model is based upon traction-free rolling and materials which are ideal elastic-plastic solids, but produces upper and lower bound solutions for groove formation and residual stress distributions which are realistic. Data for the three-dimensional problem are presented showing the process of cumulative deformation during a number of rolling cycles up to a steady state.
