Abstract EN
In the design process, one of the main targets is to reduce the peak values of the contact stresses.
This can be attained by layering the contacting bodies by layers of different material characteristics.
Viscoelastic materials are characterized by either a stress relaxation or a creep deformation; therefore, the contacting bodies can be layered with such materials to attain this target.
This paper discusses effects of the material characteristics of viscoelastic layers upon the unbounded contact configuration.
Three material parameters are considered: the layer/contact solids stiffness ratio, the delayed/instantaneous elasticity ratio, and the material relaxation time.
The results are obtained by using a two-dimensional time-dependent nonlinear computational model, developed by the authors, capable of analyzing quasistatic viscoelastic frictional contact problems.
