Computational simulation of machining
Zvěřina, Martin ; Hůlka, Jiří (referee) ; Petruška, Jindřich (advisor)
This Master’s thesis process list of different finite element programs, which allows us to simulate process of material separation. We estimated their advantages and disadvantages in the end. In program ANSYS Ls-Dyna was created 3D model, in which we simulate process of orthogonal splinter machining and we study dependence of changes different input parameters (tool geometry, depth of cut, cutting speed) on the chip form and forces rate between tool and workpiece.

Evaluation of buckling risk at beams made of two various materials
Zvěřina, Martin ; Dušek, Daniel (referee) ; Burša, Jiří (advisor)
Aim of this work is evaluation of buckling risk at beams made of two various materials and delimitation limits for critical power buckling beam from two various materials by the help of relations for prismatic beam. Further is here processed analyst determination critical force buckling for free beam from two various materials and also analyst determination critical force buckling for fixed beam from two various materials.
