materials. It is worth pointing out that Eisele and Corbach [9] also
reported the same evidence as Ostrovskii at the same time. Figure 6-8
shows some interface pressure–joint deflection curves to understand
what is different from cast iron to nonmetallic joints.
Following that the research of Ostrovskii, Dolbey and Bell [8] con-
ducted a further investigation into flat joints including those made of new

experiment, the specimens used were made of gray cast iron (BS Grade 14),
