Research issues on punch – circular plate elastic contacts

Circular plates enter into 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 some plate were reviewed in this study. For thin bodies and small transversal dimension bodies Diaconescu and Glovnea[1],[2] advanced analytical solutions solving a Boussinesq type problem for a elastic layer and a Boussinesq type problem for a cylindrical body. The obtained results satisfy all elasticity requirements so they are the searched ones. Experimental set-ups build by Glovnea [3] and Ovcharenko [4], used to investigate contact problems via laser profilometry or direct optical methods were also reviewed
