DEVELOPMENT OF A CREEP RATE POROSITY CORRECTION FACTOR Academic Article uri icon

abstract

  • A general method for constructing a creep rate porosity correction factor for any porous material has been developed. The creep rate of a porous material is assumed to be influenced by the effect of porosity on stress, diffusion coefficient and shear modulus. The effect of porosity on stress and diffusion coefficient was derived from simple physical considerations; the effect of porosity on shear modulus was addressed empirically. The resulting general method has been applied to the construction of a porosity correction factor for the creep of UO2, and comparison with experimental results shows good agreement. 1990.
