Neutral and shakedown domains of circular plates subjected to cycles of pressure and temperature

For a given relation between generalized load parameters F(T,P) = 0, called the load control program /LCP/, the neutral domains /ND/ of the elastic reponse can be evaluated. An exact method consisting in solution of the full set of plate equations for large deflections has been worked out elsewhere. In the present report an approximate method of computation of the ND curves PHIsub(i) related to the points Msub(i) on the LCP path is presented. The main idea of this method lies in superposition of appropiate basic elastic solutions and the elastic-plastic solution obtained for the fixed point Msub(i). (orig.)
