When an aircraft changes its speed or altitude, large thermal strains may be set up in the wing structure; sometimes these are of sufficient magnitude for the accompanying stresses to exceed the clastic limit of the material. During its life the aircraft may suffer a large number of cycles of thermal stress. Under repeated thermal loading it is found that four types of stress-strain system may be set up: permanent elasticity and shakedown to an clastic state, which are safe, and alternate plasticity and incremental collapse, which are dangerous. The present paper investigates these stress-strain systems and determines the conditions for their occurrence.
