Conclusions

  1. 1.

    A formula is proposed, with which the strength of porous sintered materials may be evaluated as a function of porosity, pore shape and size, nonuniformity of stress distribution over the actual specimen cross section, and specimen size.

  2. 2.

    It is shown that, if rupture of a porous specimen occurs at a cross section which has been weakened most by pores, the strength characteristics of the specimen may be expected to be influenced by its size. A formula allowing for this factor is derived.

  3. 3.

    Various analytical expressions for the distribution of stress over the actual cross section of a specimen are examined, and their connection with the type of the strength vs porosity relationship is demonstrated.
