A probabilistic Physics of Failure-based framework for fatigue life prediction of aircraft gas
turbine discs operating under uncertainty is developed. The framework incorporates the …

This paper presents an elasto-viscoplastic finite element modelling framework including the
associated UMAT codes to investigate the high-temperature behaviour of a gas turbine rotor …

Fully reversed strain controlled low cycle fatigue and creep-fatigue interaction tests have
been performed at±0.7% strain amplitude and at three different temperatures (400° C, 500° …

Frequent changes in operating conditions can result in the great loss of the service life of
gas turbines that work at high speed, high pressure, and high temperature. To improve the …

In order to meet the requirement of frequent start-stop of the units, it is significant to optimize
the operation scheme of the unit. A novel optimized mathematical model of a steam turbine …

In this paper, a new life assessment framework is proposed based on the elastic-viscoplastic
modeling and the damage behavior for the structural component under multiaxial non …

In this study, the effect of developed anisotropic damage on the ratcheting is studied.
Damage occurs during extra loading in an anisotropic manner. A modified anisotropic …

以某重型燃气轮机组合转子为研究对象, 建立了组合转子整体损伤模型; 将纯疲劳和纯蠕变的
损伤研究作为基础, 根据损伤力学累积模型将联合作用下的损伤变量表示为两种损伤的非线性 …

The rotor is the core component of a gas turbine, and more than 80% of the failures in gas
turbines occur in the rotor system, especially during the start‐up period. Therefore, the safety …

This paper presents an experimental estimation of the ductile behavior and low-cycle fatigue
life for widely used structural steels AISI 1020 and AISI 1030 based on continuum damage …
