Contact Mechanics

With the growth of computing power, numerical simulations have found their way into the analysis of almost every engineering design. This has also affected the level of modelling and with more refined models unilateral constraint conditions are now present in many types of analysis. This means that different contact conditions have to be considered in the design and analysis of engineering structures and systems.

Besides standard applications where contact constraints are present at the same length scale as the dimensions of the structure, there are many interesting and technically relevant problems involving different length scales.

Application include:

  • tyre/road contact
  • car crash analysis
  • steel high-strength friction-grip bolts
  • mechanical description of granular materials
  • coupled contact of discrete elements and continua
