Linear finite element analysis has for many years been widely used in the civil and mechanicals engineering fields and, in particular, in the construction, automotive, aerospace, and offshore sectors. Finite element analysis is an integral part of the design cycle in many companies.
Finite element programs that have the capability to solve
non-linear problems have also been available for many years but
often have been considered for use only in specialised industries
such as nuclear engineering and advanced gas turbine research. In
fact, the application of non-linear finite element analysis to
general engineering has been growing rapidly, using commercially
available packages of high quality and reliability. This book deals
specifically with the subset of non-linear problems involving
contact or friction.
In this book the aim is to give sufficient background to the
terminology and techniques specific to contact and friction
analysis. In addition typical problems areas, which may arise, are
highlighted and guidance as to how they can be resolved is
provided. A number of examples are used throughout the text to
illustrate the concepts and potential applications.
Why non-linear analysis?
- Incremental solution procedure
- Iterative behaviour
Classification of contact problems
- Normal contact detection and separation behaviour
- Tangential or sliding contact
- Friction and friction models
- Thermal contact phenomena
- Use of various element types
Approaches for contact analysis
- User modification of boundary conditions and constraints
- Non-linear springs or elastic foundations
- Contact element
- Penalty stiffness
- Lagrangian multipliers
- Contact procedures based on automatic adaptation of boundary
conditions and constraints
- Comparison of contact methodologies
- How is contact defined by the user?
- Model verification and post-processing
- The amount of deformation and sliding
- The presence of other non-linear phenomena
Complicating aspects in contact analysis and how they can be
- Handling of rigid body modes
- Amount of sliding affects choice of approach
- Large differences in stiffness or mesh density
- Contact between continuum elements, shell and beam elements
- Deformable bodies with a curved boundary contour
- Friction dominated contact
- Dynamic contact
- Thermal contact
- What accuracy can be expected?
- Contact and remeshing
