"Some Contact Problems Showing the Influences of Inhomogeneities"


In this talk the general theory of eigenstrains as developed by Mura and others will be applied to show the influence of inhomogeneities on bodies in contact.  Solutions, which have been derived for the point eigenstrain and cuboidal inclusion problems, will be utilized to solve contact problems, whose bodies may contain an inhomogeneity.  Specific examples that will be discussed are the following: 1) Contact involving two joined quarter spaces; 2) Partial-Slip contact involving an inhomogeneity; and 3) Partial-Slip contact involving plasticity.
