Damage related material constants in continuum damage mechanics for unidirectional composites with matrix cracks (2018)
Journal Article
Li, S., Wang, M., Jeanmeure, L., Sitnikova, E., Yu, F., Pan, Q., …Talreja, R. (2019). Damage related material constants in continuum damage mechanics for unidirectional composites with matrix cracks. International Journal of Damage Mechanics, 28(5), 690-707. https://doi.org/10.1177/1056789518783239

Application of a continuum damage mechanics formulation rests on the ease with which the material constants involved in the formulation can be determined. For an initially linear elastic material, the changes in elastic constants induced by damage de...

The unit cell method in predictions of thermal expansion properties of textile reinforced composites (2018)
Journal Article
Gou, J.-J., Gong, C.-L., Gu, L.-X., Li, S., & Tao, W.-Q. (2018). The unit cell method in predictions of thermal expansion properties of textile reinforced composites. Composite Structures, 195, 99-117. https://doi.org/10.1016/j.compstruct.2018.04.045

Thermal expansion properties of textile reinforced composites with certain structure symmetries can be efficiently calculated by a size-limited unit cell. In this paper, a general approach is developed for the establishment of such a unit cell model....

A critical review on the rationality of popular failure criteria for composites (2018)
Journal Article
Li, S., & Sitnikova, E. (2018). A critical review on the rationality of popular failure criteria for composites. https://doi.org/10.1016/j.coco.2018.02.002

Popular failure criteria for fibre reinforced composites are subjected to critical scrutiny on their rationality. The rationality of a theory is about the mathematical and physical logic underlying the theory, rather than the closeness of their resul...

An excursion into representative volume elements and unit cells (2017)
Book Chapter
Li, S., & Sitnikova, E. (2017). An excursion into representative volume elements and unit cells. In P. W. Beaumont, & C. H. Zweben (Eds.), Comprehensive Composite Materials II, Volume 1, Reinforcements and General Theories of Composites (451-489). Amsterdam: Elsevier. https://doi.org/10.1016/B978-0-12-803581-8.10352-2

The objective of this chapter is to provide a comprehensive and systematic account on the subject of representative volume elements (RVEs) and unit cells (UCs). To construct an RVE or UC, intuition has been often perceived sufficient to facilitate th... Read More about An excursion into representative volume elements and unit cells.

The Tsai-Wu failure criterion rationalised in the context of UD composites (2017)
Journal Article

© 2017 The Authors This paper is to rationalise the empirical aspect of the Tsai-Wu failure criterion in the context of UD composites associated with the determination of the interactive strength property F12 based on the analytic geometry. It reveal... Read More about The Tsai-Wu failure criterion rationalised in the context of UD composites.

Subtle features of delamination in cross-ply laminates due to low speed impact (2017)
Journal Article

In cross-ply laminates, the shape of delamination areas, which form due to low velocity impact, have two subtle features, which have been observed consistently in numerous experiments. Those are the pointed delamination tips and the intact zone betwe... Read More about Subtle features of delamination in cross-ply laminates due to low speed impact.

On understanding the applicability of Mohr-Coulomb failure hypothesis for composite materials using UnitCells© (2016)
Presentation / Conference Contribution
Balasubramani, N. K., Sitnikova, E., & Li, S. (2016). On understanding the applicability of Mohr-Coulomb failure hypothesis for composite materials using UnitCells©.

The applicability of Mohr-Coulomb (M-C) failure hypothesis for anisotropic composite materials is re-examined in this paper. Mohr-Coulomb failure theory has been widely referred to in the literature to study the failure of unidirectional (UD) fibre r...

Reflection on 'finite rotation problem' in plate and shell theories and in finite element formulation - Back to basics (2014)
Journal Article

This paper results from a reflection on the problem of finite rotations in plates and shells and its presentation in finite element formulation, a well-attended subject with a wide diversity of treatments, often extremely complicated. For instance, t... Read More about Reflection on 'finite rotation problem' in plate and shell theories and in finite element formulation - Back to basics.

Burst strength of carbon fibre reinforced HDPE strip pipeline repair system: a numerical and experimental approach (2014)
Journal Article

Oil and gas pipelines are susceptible to various forms of damage where repair mechanisms have since been developed for rehabilitation. Once installed, structural health monitoring often incurs excessive costs and defects rectification of the repaired...
