A Coupled Creep-plasticity Model for Residual Stress Relaxation of a Shot-peened Nickel-base Superalloy
A COUPLED CREEP-PLASTICITY MODEL FOR RESIDUAL STRESS RELAXATION OF A SHOT-PEENED NICKEL-BASE SUPERALLOY Name: Dennis Justin Buchanan University of Dayton, 2007 Advisor: Dr. R. A. Brockman Shot peening has been employed in numerous industries for decades to impart beneficial compressive residual stresses on the surface of metal components. Compressive residual stresses retard initiation of surfa...

متن کاملRecent Advances in Creep Modelling of the Nickel Base Superalloy, Alloy 720Li
Recent work in the creep field has indicated that the traditional methodologies involving power law equations are not sufficient to describe wide ranging creep behaviour. More recent approaches such as the Wilshire equations however, have shown promise in a wide range of materials, particularly in extrapolation of short term results to long term predictions. In the aerospace industry however, l...
متن کاملModelling of constitutive and fatigue behaviour of a single-crystal nickel-base superalloy
In this licentiate thesis the work done in the project KME410 will be presented. The overall objective of this project is to evaluate and develop tools for designing against fatigue in single-crystal nickel-base superalloys in gas turbines. Experiments have been done on single-crystal nickel-base superalloy specimens in order to investigate the mechanical behaviour of the material. The constitu...
متن کاملFatigue Behavior and Life Prediction Model of a Nickel-Base Superalloy under Different Strain Conditions
The fatigue behavior of a nickel-base superalloy was investigated under total strain-controlled mode at high temperature. The fatigue life, cyclic stress response behavior and hysteresis loop of the superalloy were investigated under isothermal low cycle fatigue (LCF) conditions. The superalloy exhibited cyclic hardening and softening behaviors during the process of fatigue loading. The hystere...
