title = "EFFECTS OF PORE SHAPES ON LOW FREQUENCY WAVE SPEEDS IN POROUS MEDIA.",

abstract = "The author considers the propagation of low frequency elastic waves in porous media with emphasis on the effect of the pore shape on the effective wave speeds. Previous studies on elastic waves in porous materials have usually considered the pores as spherical. This assumption of spherical pores may be valid in particular materials at very low porosities ( less than 5%). As an example, the pores in metal sintered at high temperatures for long times are nearly spherical. However, in many porous materials, and generally at higher values of porosity ( greater than 5%), this assumption is not valid. As the porosity increases, overlapping pores produce complicated pore shapes. Photomicrographs of iron compacts at 6. 2% porosity clearly show the pores as non-spherical. In this paper the author limits his attention to pores in the shape of spheroids with any aspect ratio.",
