EFFECT OF THE HISTORY OF STRESSING ON THE STRESSED STATE OF A DOUBLE LAYER SHELL,
Abstract
It is known, that in a majority of structural load cases, the loads change nonproportionally with respect to one parameter. Such stressing is called complex, in contrast to simple stress, when all the loads are proportional relative to one single parameter. If in elastic problems, the order of applying stress, i.e., the history of stressing, shows no effect on the resultant stressed state, then beyond the limit of proportionally is observed a different picture. Here, depending upon the stressing history variants, can be found entirely different stressed states. From this viewpoint, a problem of a stressed state of a double layer shell is discussed; to such an arrangement can be for example, brought the construction of a liquid rocket engine combustion chamber. The stressing factors basically can be reduced to two - internal pressure and irregular heating of shells. Complex stressing takes place, for example, during the starting of the liquid rocket engine engine, when the temperature and internal pressure rise nonproportionally with respect to the general parameter.
