Kojos protezo deformacijų skaičiavimas baigtinių elementų metodu

Abstract

The article analyses stress and deformation of leg's prosthesis sleeve and stump skin and soft tissues' at contact place, evaluating non-linear systems. Stump skin and soft tissues' and prosthesis sleeve contact rigidity was exxamined by applying digital method ANSYS program package of finite elements. Rezults of leg's prosthesis sleeve and stump skin and soft tissues' contact of non-linear system analysis presented, that the size of maximum deformation is 1,3 less then in case of linear system, maximum stress decreases 1,2 times. That's why non-linear sampler has to be used for definite calculation of contact deformation.
