STRESS DISTRIBUTION IN MULTI-CELLULAR TORQUE BOXES DUE TO PRIMARY AND SECONDARY CREEP

摘要

This paper is concerned with the stress analysis of multi-cellular torque boxes in the presence of primary as well as secondary creep. The elas¬tic analog is used to reduce the creep problem to one of nonlinear elasticity. The results indicate that depending upon the geometry of the structure the stress distribution can differ appreciably from that given by linear theory, Furthermore, the deformation caused by creep can be significant.
