Chamakura, J.N. (author), Riemslag, A.C. (author), Reinton, T.E. (author), Popovich, V. (author), Sietsma, J. (author)The reversible behaviour of metals at low applied stresses is more complex than the generally assumed linear behaviour. This is primarily because of the reversible nature of dislocation motion leading to a strain contribution known as anelasticity. This work aims to investigate (a) quantification of dislocation structures in industrial grade...journal article 2022

Kestens, L.A.I. (author), Nguyen-Minh, Tuan (author), Petrov, R.H. (author)The present paper investigates the role of parent phase topology on a crystallographic variant selection rule. This rule assumes that product phase nuclei appear at certain grain boundaries in the parent structure, such that a specific crystallographic orientation relationship is observed with both parent grains at either side of the grain...journal article 2022

Kavoura, Dr. Florentia (author), Veljkovic, M. (author)The demountable and reusable steel-concrete composite structures contribute immensely at the sustainable development in construction. The main technical practice which allows for demountability and reusability is the use of demountable shear connectors in their floor systems. These demountable shear connectors can satisfy the need for composite...conference paper 2022

Abraham Mathews, J. (author), Sietsma, J. (author), Petrov, R.H. (author), Santofimia, Maria Jesus (author)Bainite to austenite reversal is one of the grain refinement techniques employed in carburized steels. However, chemical segregation influences the homogeneity of the bainitic structure, which is seminal to exploit the advantages associated with austenite reversal. It is therefore important to understand the influence of chemical segregation...journal article 2022

Yan, R. (author), Xin, Haohui (author), Mela, Kristo (author), El Bamby, H. (author), Veljkovic, M. (author)A welded rectangular hollow section (RHS) X-joint exposed to tension loading has three typical fracture-related failure modes: Punching shear failure (PSF), Brace failure (BF), and Chord side wall failure (CSWF). Prediction of these failure modes by finite element (FE) simulations requires modelling of the material damage. An appropriate...journal article 2022
