چکیده
This paper presents the development of finite element software for creep deformation and damage analysis of weldment. The development and benchmark test of the software under plane stress, plane strain, axisymmetric, and 3 dimensional cases were reported in previous work [1]. This paper primarily consists of two parts: 1) the structure of the new FE software and the existing FE library applied in obtaining such computational tool via an approach for stress and field variable updating; 2) the development and validation of stress update; and 3) the development of validation of multi-material zones version. This paper contributes to the computational creep damage mechanics in general and particular to the design and the development of finite element software for creep damage analysis of multi-material zone.

Creep Life Forecasting of Weldment
One of the yet unresolved engineering problems is forecasting the creep lives of weldment in a pragmatic way with sufficient accuracy. There are number of obstacles to circumvent including: complex material behavior, lack of accurate knowledge about the creep material behavior specially about the heat affected zones (HAZ),accurate and multi-axial creep damage models, etc. In general, creep life...
متن کاملThe development of computational FE system for creep damage analysis of weldment
A Finite Element Analysis (FEA) system was designed for the analysis of creep deformation and damage evolution in weldment. This project essentially consists of three parts which involves 1) transfer programme development, 2) numerical integration subroutine development, and 3) validation of complete FEA system. Firstly, the development of a user-friendly preand postprocessing transfer programm...

Underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. Gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. The Fischells Brook area is a pillow-shaped body of salts located in the St. George's Bay area of southwest Newfo...
