THERMO-ELASTIC EXPANSION OF FINITE CYLINDERS.
Technical Report
·
OSTI ID:4350900
The thermal expansion of finite cylinders is calculated by a numerical method using a suitably chosen power polynomial whose coefficients are found by a rigorous application of the boundary conditions and minimizing the total strain energy. Calculations were done for several length-to-diameter ratios, and it was found that in every case (a) the greatest radial expansion occurs at the ends of the cylinder and (b) the radial and tangential stresses are everywhere tensile on the end-faces. Its relevance to circumferential ridging on the cladding of fuel elements is discussed briefly. (auth)
