Study on Contact Strengths of Thick-Walled Cellular Solids with Irregular Pores Structures

Article Preview

Abstract:

For improving contact strength of the thick-walled cellular solid with irregular pores structures, which is used in high temperature self-compensating lubricating environment, a concept of relative porosity ratio αi was proposed to describe the proportion of the porosity φi of the each shape pores in the materials to the total porosity φ of the materials. The results show that the characteristic value of αi, the distribute radius and regularity as well as the orientation of pores affected the contact strength strongly. The cracks phenomenon of the materials was also observed by experiments.
