Area of interest - Development of fatigue cracks in the uniaxial and multiaxial loading. In this area: stress approach, crack tip opening displacement and energy approach as well as fatigue crack growth rate models, strain and stress at the crack area, fatigue life. The criteria of fatigue cracking in mixed mode. The influence of the material structure on the crack paths and the effect of stress concentrators factor on fatigue life. Numerical Methods.
Numerical analysis of stress and strain in specimens with rectangular cross-section subjected to torsion and bending with torsion
