Journal ArticleDOI
An algorithm for modelling microstructural development in weld heat-affected zones (part a) reaction kinetics
TL;DR: A computer algorithm originally developed for predicting the hardenability of low alloy steels has been adapted to forecast the microstructural development in weld heat-affected zones (HAZ) as mentioned in this paper.
Journal ArticleDOI
Creep deformation due to a viscous grain boundary phase
TL;DR: In this article, the deformation of a two-phase material composed of rigid grains embedded in a contiguous viscous matrix is analyzed, using two different models: mean field treatment and a second treatment of a periodic array of hexagonal grains.
Journal ArticleDOI
Coupled transient heat transfer—microstructure weld computations (part B)
TL;DR: In this article, the Watt/Coon algorithm is coupled with a transient finite element heat transfer analysis for computing the microstructure as a function of space and time ( x, y, z, t ) in the heat-affected zone (HAZ) of low alloy steel welds.
Journal ArticleDOI
On the stress and strain fields ahead of a stationary crack in creeping solids.
TL;DR: In this paper, a set of finite-element calculations has been performed to assess the validity of several commonly used crack tip parameters for creeping solids and derive a new crack tip parameter, a modified amplitude of the HRR field which equals C ∗ once a steady state is achieved.
Book ChapterDOI
A Numerical Study of Crack Tip Parameters in Creeping Solids
TL;DR: The crack tip parameters commonly used when attempting to correlate crack growth rate are the stress intensity factor K [1], the net section stress [2], the crack tip opening displacement rate [3,4] and C* [5,6], the rate dependent Jintegral.
