abstract = {The strain-life approach is one of the most commonly used methods for evaluating component fatigue. In its application for thermo-mechanically load states and for modelling local temperature stress-strain states, we use a stress-controlled rheological spring-slider model with an operator of the Prandtl type, which makes it possible to model the elasto-plastic material properties. The approach is used to evaluate complex components in combination with the finite-element method (FEM). The described evaluation approach is classified as one of the non-unified procedures, where we can determine separately the stress-strain states and separately calculate the damage. For the damage calculation a Damage Calculation Program (DCP) was developed. It has the possibility to import the results acquired by linear or nonlinear FEM analysis. The critical areas are determined by using a deformation endurance curve and the Skelton approach. The material data on non-measured temperatures is interpolated with the linear or cubic Hermite method. The application of the developed model is shown on two standard-shaped test specimens for deformation control tests in a constant temperature field and for a combination of the random temperature history and the mechanical load. The temperature dependence of the Kp parameter used in the Neuber formula, for estimating the elasto-plastic stress-strain, states from the results of the linear FEM analysis is also included in the research. The described procedure enables a fast numerical validation with a random combination of temperature and mechanical load. },

The strain-life approach is one of the most commonly used methods for evaluating component fatigue. In its application for thermo-mechanically load states and for modelling local temperature stress-strain states, we use a stress-controlled rheological spring-slider model with an operator of the Prandtl type, which makes it possible to model the elasto-plastic material properties. The approach is used to evaluate complex components in combination with the finite-element method (FEM). The described evaluation approach is classified as one of the non-unified procedures, where we can determine separately the stress-strain states and separately calculate the damage. For the damage calculation a Damage Calculation Program (DCP) was developed. It has the possibility to import the results acquired by linear or nonlinear FEM analysis. The critical areas are determined by using a deformation endurance curve and the Skelton approach. The material data on non-measured temperatures is interpolated with the linear or cubic Hermite method. The application of the developed model is shown on two standard-shaped test specimens for deformation control tests in a constant temperature field and for a combination of the random temperature history and the mechanical load.
