On Selection of the Model of Limiting State of Heat-Resistant Materials Under Uniaxial Asymmetric Loading

The limiting state of specimens made of heat-resistant nickel alloys under the combined action of static and cyclic loading in a wide range of temperatures is studied. The solution is constructed using the model of limiting state that relates the ultimate stresses in the form of exponential transcen...

Description
Summary:The limiting state of specimens made of heat-resistant nickel alloys under the combined action of static and cyclic loading in a wide range of temperatures is studied. The solution is constructed using the model of limiting state that relates the ultimate stresses in the form of exponential transcendent function. Computational results are validated experimentally for solid prismatic specimens.
