| dc.description.abstract | A review has been undertaken of recently published
data on ultrasonic velocity-porosity for a variety of
porous ceramic materials, including information on pore
structure. These experimental data have been compared
with data calculated using a spheroidal pore model
incorporating information on pore volume fraction,
shape, and orientation. Good agreement is obtained
between experimental and calculated values, especially
when fractional porosity is less than about 0'25, even
when a single 'effective' pore shape is employed in the
calculation. The agreement improves if a different pore
shape for each porosity level (point by point analysis)
is used. The predictive ability of the spheroidal pore
model is thus demonstrated. | en |
