摘要: Effect of initial interference fit on pull-out strength in cementless fixation between bovine tibia and smooth stainless steel post was investigated this study. Compressive behavior spongious bone studied using mechanical testing order to evaluate the elastic-plastic properties different regions proximal tibia. Friction tests were carried out aim friction contact steel. A cylindrical inserted a pre-drilled with an taken as vitro model assess contribution stability Total Knee Arthroplasty (TKA) tibial component. Pull-out experiments for fits. Finite Element Models (FEM) local developed analysis experimental ultimate force results. At post/bone interface, Coulomb considered FEM calculations pressure-dependent coefficient. It found that results are good agreement The interfacial stresses indicates micro-slip initiation depends properties.
