Many physical systems require the description of mechanical
interaction across interfaces if they are to be successfully
analyzed. Examples in the engineered world range from the design of
prosthetics in biomedical engi neering (e. g. , hip replacements);
to characterization of the response and durability of head/disk
interfaces in computer magnetic storage devices; to development of
pneumatic tires with better handling characteristics and increased
longevity in automotive engineering; to description of the adhe
sion and/or relative slip between concrete and reinforcing steel in
structural engineering. Such mechanical interactions, often called
contact/impact in teractions, usually necessitate at minimum the
determination of areas over which compressive pressures must act to
prevent interpenetration of the mechanical entities involved.
Depending on the application, frictional be havior, transient
interaction of interfaces with their surroundings (e. g. , in
termittent stick/slip), thermo-mechanical coupling, interaction
with an in tervening lubricant and/or fluid layer, and damage of
the interface (i. e. , wear) may also be featured. When taken
together (or even separately!), these features have the effect of
making the equations of mechanical evolu tion not only highly
nonlinear, but highly nonsmooth as well. While many modern
engineering simulation packages possess impressive capabilities in
the general area of nonlinear mechanics, it can be contended that
methodologies typically utilized for contact interactions are
relatively immature in comparison to other components of a
nonlinear finite element package, such as large deformation
kinematics, inelastic material modeling, nonlinear equation
solving, or linear solver technology.
