Hr. Chen et al., EFFECT OF IMPERFECT INTERPHASE ON OVERALL AVERAGE MECHANICAL-PROPERTIES AND LOCAL STRESS-FIELDS OF MULTIPHASE COMPOSITE-MATERIALS, Composites, 26(5), 1995, pp. 347-353
The effect of an imperfect interphase on the overall average transvers
e mechanical properties of multiphase composite materials is investiga
ted using a generalized self-consistent iterative method, which is dev
eloped on the basis of earlier work by the present authors. Numerical
results are presented for typical composite materials with different v
olume fractions and characteristics of imperfect interphase. The numer
ical evaluation has shown that the extent and thickness of the imperfe
ct interphase may have a significant effect on the overall average tra
nsverse plane strain bulk and shear moduli. The paper is also concerne
d with the evaluation of local stress fields in the imperfect interpha
se region.
