A study of the stress field near the stress concentrator at the bi-material interface
Krepl, Ondřej ; Klusák, Jan (referee) ; Profant, Tomáš (advisor)
The aim of this work is the solution of problems of the stress distribution near bimaterial notch tip or eventually the crack impinging orthogonaly the bimaterial interface, determination of stress singularity exponent. The first part is concerned with basics of linear elastic fracture mechanics, i.e. Irwin's concept of stress intensity factor. The second part is devoted to description of anisotropic materials by complex potencial theory. The final part is focused on calculation of eigenvalues of both isotropic and anisotropic materials and application of LES formalism on the calculation of stress singularities of the bimaterial ortotropic notch or the crack impinging orthogonaly the bimaterial interface.

Stress concentrators in aircraft structures
Černota, Jiří ; Pejchar, Jan (referee) ; Augustin, Petr (advisor)
This bachelor´s thesis deals with significant stress concentrators in compossed plane constructions made of metal materials. It generates summary of the most significant notches and their effect on fatigue life. It further states opportunities of description of constructional solution leading to reduction of stress concentration.
