Flame Forming

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.

In this paper, the nonlinear transient thermal stress analysis is conducted for temperature-dependent hollow cylinders subjected to a decaying-with-time thermal field. By the finite element method, the highly nonlinear governing equations are solved. The time histories of temperature, displacement, and stress due to the decaying-with-time thermal load are computed. A sensitivity analysis includes the effects of exponent of the decayed heat flux and temperature-dependency of density and material properties is carried out. Numerical results show some interesting characteristics of the thermoelastic behaviors of the hollow cylinders studied. In particular, the effect of temperature-dependency of the material properties on the thermoelastic parameters was demonstrated to be significant.
