The model allows for temperature gradients within structural member cross-sections and for bending of the members themselves. Nonlinear effects such as radiation boundary conditions and temperature-dependent material properties are included. The problem chosen is that of a long cantilevered lattice beam in a geosychronous orbit. For the structure and loading chosen, no significant dynamic responses such as vibration occurred. Thermally-induced axial forces were the predominant type of loading. The magnitude of axial stresses generated by the transition from shadow to sunlight is on the order of 30% of yield stress.
