    Review of methods for local contact search

  • Original language description

    The local contact search is a numerical procedure of a contact algorithm which is used for computing of a penetration vector between so-called master and slave segments of contact surfaces. There are several approaches. In this paper the minimum distanceproblem between the master segment and the integration point of the slave segment is used. For quadrilateral elements this approach leads to the system of two nonlinear equations. For its solution several methods was tested (Newton-Raphson method, leastsquare projection, method of steepest descent, Broyden's method, BFGS method, DFP method and simplex method) and efficiency was compared.
