Towards understanding the influence of porosity on mechanical and fracture behaviour of quasi-brittle materials: experiments and modelling
TL;DR: Based on the known porosity, a 3D model of each microstructure has been built and the deformation and fracture was computed using a lattice-based multi-scale finite element model, which predicted similar trends as the experimental results and was able to quantify the fractured sites.

- 01 Jan 2003
TL;DR: The full range of techniques available for the investigation of materials structure and accurate quantitative determination of microstructural features within materials can be found in this article, which is the best introductory resource for understanding the interrelationship between microstructure and physical, mechanical, and chemical properties, as well as selection and application of techniques for both basic and applied studies.

Properties and evolution of sessile interstitial clusters produced by displacement cascades in α-iron
TL;DR: In this article, the thermal stability of three common forms of sessile clusters has been investigated, and the lifetime and activation energy for transforming into glissile form have been estimated.

A.H. Yaghi,Thomas H. Hyde,Adib A. Becker,Wei Sun,G Hilson,Sarinova Simandjuntak,Peter E J Flewitt,Martyn J Pavier,David J. Smith +8 more
TL;DR: In this article, the residual macrostresses in a multipass circumferentially butt-welded P91 ferritic steel pipe have been determined numerically and experimentally.

Computational modelling of fracture in polycrystalline materials
TL;DR: A brief survey of the computational methods used to model fracture in polycrystalline materials can be found in this paper, where the authors investigate the propagation of cleavage cracks across grain boundaries, study the influence of texture, grain shape, impurity segregation and prior creep cavitation, and examine the ductile-to-brittle transition region in ferritic steels.
