  • Crack growth in FeP04 steel under cyclic tension for different notches on the basis of its microstructure 
    Rozumek, D. (Проблемы прочности, 2008)
    We present the results of experimental work carried out in order to analyze the initiation and propagation of fatigue cracks in FeP04 steel. The tests were performed in plane specimens under cyclic tension by keeping ...
  • Fatigue crack growth in AlCu4Mg1 under nonproportional bending with torsion loading 
    Rozumek, D.; Marciniak, Z. (Фізико-хімічна механіка матеріалів, 2010)
    The paper presents the experimental results of fatigue crack growth on AlCu4Mg1 aluminium alloy under proportional and non-proportional bending with torsion obtained at Opole University of Technology. Specimens with square ...
  • Fatigue properties of notched specimens made of FeP04 steel 
    Rozumek, D.; Marciniak, Z. (Фізико-хімічна механіка матеріалів, 2011)
    Fatigue properties of the specimens with different notches made of FeP04 steel are presented. The specimens ware characterized by double symmetric lateral notches with a notch root radius ranging from ρ = 0.2 to 10 mm. The ...
  • Influence of oxygenation time on crack growth in titanium alloy under cyclic bending 
    Rozumek, D.; Hepner, M. (Фізико-хімічна механіка матеріалів, 2011)
    The paper contains the results of tests on the fatigue crack growth in Ti–6Al–4V titanium alloy. Plane specimens of 4 mm in thickness with a unilateral notch were used. An analysis of crack growth was carried out for ...
  • Review of formulas to describe the fatigue crack growth rate 
    Rozumek, D. (Фізико-хімічна механіка матеріалів, 2013)
    The paper presents a review of formulas of fatigue crack growth rate. The equations are divided into three groups according to the fatigue damage parameters used, i.e. stress, strain or displacement and energy. The parameter ...
