| dc.description.abstract | The results of experimental and analytical study of cracking threshold for cast iron with defects have been presented. The mechanical properties indices (σu ≈ 950MPa) and microstructure of spheroid graphite iron have been estimated. CT specimens from cast iron with defects and cast iron without defects have been tested. Dependencies between crack growth rate and threshold for specimens with shrinkage voids and without them have been obtained. Threshold values are obtained when the crack growth rate is v=10-10 m/cycle, v=10-11 m/cycle and v=10-12 m/cycle. | eng |
| dc.description.abstract | Pateikiami duomenys apie ketaus su defektais pleišėjimo slenksčio eksperimentinį ir analitinį tyrimą. Nustatyti stipriojo ketaus mechaninių savybių rodikliai (σu ≈ 950 MPa) ir mikrostruktūra. Išbandyti CT bandiniai iš ketaus be defektų ir ketaus su defektais. Sudarytos priklausomybės tarp plyšio plitimo greičio ir įtempių intensyvumo koeficiento intervalo bandiniams su tuštumų tipo defektais ir be jų. Gautos pleišėjimo slenksčio ΔKth reikšmės, kai plyšio plitimo greitis v = 10 -10 m/ciklą, v = 10-11 m/ciklą ir v = 10-12 m/ciklą. | lit |
