In the first paper, a new multiaxial distribution function having location parameters was formulated involving both effects of internal and surface cracks. Using this new distribution function, fracture probability ratios under biaxial tension and expected fracture loci under biaxial stresses are calculated, and the following results are obtained. (1) Fracture probability ratios increase as the principal stress ratio tends to unity. (2) Fracture probability ratios tend to zero as the stress level ratios tend to unity. (3) The expected fracture stress under uniaxial tension coincides with that under equi-biaxial tension as a shape parameter or a location parameter tends to unity ; namely, the expected fracture stress in any tensile stress state should coincide with each other.
