Semi-analytical methods are a common
way of solving non-hertzian contact problems when
designing mechanical components. These methods
require of the discretization of the domain into a set of
pressure elements and their accuracy and computational
cost are related to the number of elements in
which the domain is discretized. But, while the
accuracy increases as the pressure element mesh is
refined, the computational cost increases quadratically
with the number of pressure elements. So in the great
majority of the cases, a commitment between accuracy
and computational cost must be achieved. In this work,
a new approach has been developed to improve the
performance of semi-analytical methods for solving
contact problems. This approach uses an adaptive
mesh refinement strategy, based on the quadtree
decomposition of the domain. As a result, the computational
cost decreases, while the accuracy of the
method remains constant. [-]
