For a measurement the testing system MTS Mini Bionix 858.2 was used. The specimens were clamped by new jaws which were developed by modifying of lathe chuck and were suggested replaceable plastic and metal contact surfaces with trapezoid and rounded profile. Furthermore the theoretical comparing of these profiles and the derivation of relation for minimal demand on coefficient of friction depending on applied forces and angle of profile are in the text. For experimental comparing of profiles the tensile forces were obtained, 1462.4N for plastic and 1437.0N for metal rounded contact surfaces. The similar results are probably reason of reaching sufficient area of frictional surface for tested tendons. The mentioned area was already reached for geometry of metal component which had smaller height."@en . . . . . "[5DCAB6F70F5E]" . "21220" . "Praha" . . "Praha" .
