Abstract

Shakedown theory determines the load limits for structures under variable loads. Our recently-constructed reduced shakedown kinematic formulations are re-examined, with particular expressions constructed for plane stress problems in both cases of Mises and Tresca materials. While the possibilities for numerical implementations of the reduced forms are to be explored, we illustrate the applications of the forms to estimate the nonshakedown loads for a circular hollow disk under variable pressure and temperature fields.
