Investigation of the mechanical interaction of the trabecular core with an external shell using rapid prototype and finite element models
The mechanical properties of vertebral bone have been widely studied with the ultimate goal of improving fracture risk prediction. However, the mechanical interaction between the cortical shell and the trabecular core is ...
Predictions of ICHAZ cyclic thermo-mechanical response in GTAW process for 9Cr steels
(ASME The American Society of Mechanical Engineers, 2019-02-25)
This work is concerned with the development of a modeling framework to predict the effects of tempered–untempered martensite heterogeneity on the thermomechanical performance of welded material. A physically based ...
A process-structure-property model for welding of 9Cr power plant components: The influence of welding process temperatures on in-service cyclic plasticity response
A process-structure-property methodology is presented for welding of 9Cr steels under representative flexible operating conditions for a typical thermal power plant girth-welded pipe. The welding-induced evolution of ...
A through-process, thermomechanical model for predicting welding-induced microstructure evolution and post-weld high-temperature fatigue response
This paper is concerned with the development of a modelling framework to predict the effects of welding and post-weld heat treatment on thereto-mechanical performance of welded material, as a step towards a design tool for ...
Thermomechanical modelling for the linear friction welding process of Ni-based superalloy and verification
(SAGE Publications, 2020-01-22)
This paper presents a fully coupled thermomechanical model for the linear friction welding process of Inconel-718 nickel-based superalloy by using the finite element method. Friction heat, plastic work, and contact formulation ...
A review of thermal, microstructural and constitutive modelling of 9Cr steel for power plant applications: Towards a through-process model for structural integrity of welded connections
Life prediction for 9Cr steel welded components is an important issue facing power plant as it moves from steady-state, base-load operation to transient, flexible operation. Welding and heat-treatment of 9Cr components ...
