CALCULATION OF STRESSES AND STRAINS DEVELOPING IN FREEZING OF WATER IN CLOSED VESSELSM. K. Zhekamukhov and Kh. B. Shokarov UDC 536.44:539.37/38 The pressures in the liquid core and the breaking stresses in vessel walls developing in symmetric freezing of water in spherically and cylindrically shaped bottles are calculated. It is shown that at surface temperatures of the bottle above 20oC the water in it freezes only partially; at lower temperatures, the pressure in the liquid core attains a maximum value of about 2000 atm, which is preserved until the water freezes completely.
