Cigas S. Determination of low cycle straining parameters for weld metals of stainless steel: Master thesis of mechanical engineer / research advisor associate professor dr. R. Šniuolis; Šiauliai University, Technological Faculty, Mechanical Engineering Department.–Šiauliai, 2005.-68p.
Strain and stress change during the exploitation depend on the type of material (hardening, softening or cyclically stabile), that is chosen for the constructions in low cycle loading. If we know the type of the material, we can determine the possibility of its application in concrete exploitation conditions. Real working conditions of the most constructions are close to loading with limited strain (hard straining), because elastic and plastic deformation is met in the zones of crack and stress concentration, that are surrounded with elastically deformed material.
Analytical dependences between stress and strain in any semicycle k are expressed by summarized low cyclic stress strain curve. The low cycle loading curves parameters A, and are used for the computation of this curve. These parameters were obtained from the low cycle straining results. The other possible ways for the determination of parameters A, , and statistical methods for the evaluation of these parameters for weld metals of stainless steel at room temperature are presented in this work.
Cyclic characteristics A, and were determined by methods shown in this work. It was determined, that the values of cyclic strain and... [to full text]
