Stress and strain analysis of femoral intramedullary nail fixation and tapes
Lamrich, Martin ; Marcián, Petr (referee) ; Florian, Zdeněk (advisor)
The presented Master’s Thesis aims at determining stress and strain analysis of femur with fracture fixed by intramedullary nail and cerclage cable. The one of the goals of this work was create computational model which will be able simulate problem. Computational model consist of model of femur , it’s geometry was created on basis of CT data, than there was created model of intramedullary nail and cerclage cable on a basis of real objects. In this work was created simply model of femur with the same material features and characteristic proportions as analyzed model of femur. On this model was investigated direct impact of cerclage cables on deformation, respectively displacement in a surroundings of femoral fracture. On a final model were applied the real loads conditions. Preload in a cerclage cable was simulated by cooling down to a temperature from analytical calculation. Concluding analysis was powered by Finite Element Method (FEM) applied in system ANSYS Workbench 14.5 . Due to a results of analysis, we could say that using cerclage cables in combination with intramedullary nail is an effective way for healing femoral shaft fractures.

Methods of solving stress rods bar system
Lamrich, Martin ; Krpalek, David (referee) ; Florian, Zdeněk (advisor)
The bacalors thesis deals with methods of solving stress rod bar systems and their mutual comparasion. In the first part of this work is mentioned theoretical basic for the subsequent calculations. Graphical, analytical and numerical methods of solving stress rod bar systems are applied to representative examples. Each of the examples contains theoretical part where are mentioned advantages, disadvantages and suitability for use of the methods. Due to Finite Element Method in ANSYS software is carried out a numerical calculation on the solved rod bar systems. Conclusion is intent on summary of work and comparation of results. Analytical calculations were carried out in MATHCAD 14 software.
