The Real Area of Contact Measured on Elastomers

摘要: In this paper optical profilometry is used to measure the roughness deformation of a rough elastomer in contact with smooth glass plate. Two conditions are considered: wet and dry contact. contact, deformed texture hardly influenced by load. This probably caused high stiffness liquid film, compared asperity bulk stiffness. increased flattening observed increasing Besides, different deformations occur at length scales: Small scale asperities still persist on extensively flattened larger asperities. interaction, which will be more significant smaller scales, where distance between height.
