Research Issues on Punch - Circular Plate Elastic Contacts

Abstract

Circular plates enter into the category of finite dimension bodies. Solutions regarding the displacements and stresses, which appear at the contact involving finite dimension bodies and also numerical and analytical results regarding several plates were reviewed in this study. For thin bodies and small transversal dimension bodie,s Diaconescu and Glovnea advanced analytical solutions solving a Boussinesq type problem for an elastic layer and a Boussinesq type problem for a cylindrical body. The obtained results satisfy all elasticity requirements, thus they are the searched ones. Experimental set-ups built by Glovnea and Ovcharenko, used to investigate contact problems via laser profilometry or direct optical methods, were also reviewed.
