Propagation of Fatigue Cracks under Multiaxial Loading
Václavík, Martin
Work is aimed at fatigue properties of the steel 11523.1 specimens under alternating push-pull and torsion. Velicity, direction and inicialization location of a fatigue crack is detected. Results are compared to predicted values acording to various accesses and authors.
The Elastic Wave Propagation in Prismatic Bodies with the Shape Transition
Morávka, Š. ; Hora, Petr
The work treats the elastic wave propagation in the basic elements of structures. Results of analytical computations (generalized ray theory), numerical simulations (FEM implemented in MARC/MENTAT) and experimental results (broadband piezoceramic transducers) are compared mutually. Samples with the most commom shape transitions are used.
The elastic wave propagation over the shape transitions of bodies
Morávka, Š. ; Hora, Petr
The work treats the elastic wave propagation in the basic construction elements of structures. The samples with the most common shape transitions are used. Results of analytical computations, numerical simulations and experimental results are verified and compared mutually. The generalized ray theory, the FEM (implemented in software MARC/MENTAT)and the transient piezoceramic transducers are used.
