| dc.description.abstract | The paper presents the data on the resistance to cycle loads of welded steel plates of double-welded, heat-treated and rewelded (repaired) joints. The microstructure and mechanical properties of the basic metal and the weld have been estimated and the results of high-cycle fatigue experimental and analytical research have been presented. By testing compact tensile specimens CT, threshold values are obtained when the crack growth rate is near v = 10-12 m/cycle. It has been found that, depending on the location of the plane of crack propagation in the joint, the threshold varies from 5.7 MPam till 23 MPam in differently obtained welds. | eng |
| dc.description.abstract | Straipsnyje pateikiami duomenys apie suvirintų plieno plokščių, dvigubo virinimo jungties, termiškai apdorotos jungties ir pervirintos (remontuotos) jungties atsparumą cikliniam apkrovimui. Nustatyta medžiagos ir siūlės mikrostruktūra ir mechaninių savybių rodikliai, pateikiami daugiaciklio nuovargio eksperimentinio ir analitinio tyrimo rezultatai. Išbandžius kompaktinius necentrinio tempimo CT bandinius, gautos pleišėjimo slenksčio ΔKth vertės, kai plyšio plitimo greitis artimas v = 10-12 m/ciklą. Nustatyta, kad priklausomai nuo plyšio plitimo plokštumos padėties skirtingai paruoštų virintųjų jungčių siūlėje pleišėjimo slenkstis kinta nuo 5.7 MPam iki 23 MPam. | lit |
