Unveiling the deformability of mussel plaque core: the role of pore distribution and hierarchical structure (2024)
Journal Article
Lyu, Y., Tan, M., Pang, Y., Sun, W., Li, S., & Liu, T. (in press). Unveiling the deformability of mussel plaque core: the role of pore distribution and hierarchical structure. Soft Matter, https://doi.org/10.1039/d4sm00832d

The mussel thread-plaque system exhibits strong adhesion and high deformability, allowing it to adhere to various surfaces. While the microstructure of plaques has been thoroughly studied, the effect of their unique porous structure on the high defor...

Validation of the fully rationalized Tsai-Wu failure criterion for unidirectional laminates under multiaxial stress states through a ring-on-ring test (2024)
Journal Article
Li, J., Yan, S., Kong, W., & Li, S. (2024). Validation of the fully rationalized Tsai-Wu failure criterion for unidirectional laminates under multiaxial stress states through a ring-on-ring test. Composites Science and Technology, 257, Article 110813. https://doi.org/10.1016/j.compscitech.2024.110813

Validating a failure criterion under complex stress states is important because composites often encounter multiaxial stress in practical applications, but it also helps to expose any deficiencies of the criterion in failure prediction in the presenc...

Stress or strain? (2024)
Journal Article
Li, S. (2024). Stress or strain?. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 480(2295), Article 20240269. https://doi.org/10.1098/rspa.2024.0269

This article is intended to reconcile the stress-based and strain-based formulations for material failure criteria, where a long-standing and deep division is present. The two approaches do not naturally agree with each other, and they do not genuine... Read More about Stress or strain?.

Characterisation of 3D woven textile composites in presence of minor weft tow undulations and cross-section variations (2024)
Journal Article
Xu, M., Sitnikova, E., Kong, W., Zhang, J., Hu, S., & Li, S. (2024). Characterisation of 3D woven textile composites in presence of minor weft tow undulations and cross-section variations. Journal of Composite Materials, https://doi.org/10.1177/00219983241270939

Weft tows in 3D woven composites are commonly approximated as perfectly straight, but their undulations are inevitable in reality, although the extent of undulations in the weft tows is not as pronounced as in the warp tows. Such minor undulations in... Read More about Characterisation of 3D woven textile composites in presence of minor weft tow undulations and cross-section variations.

Stress Invariants and Invariants of the Failure Envelope as a Quadric Surface: Their Significances in the Formulation of a Rational Failure Criterion (2024)
Journal Article
Li, S. (2024). Stress Invariants and Invariants of the Failure Envelope as a Quadric Surface: Their Significances in the Formulation of a Rational Failure Criterion. Mechanics of Materials, 196, Article 105076. https://doi.org/10.1016/j.mechmat.2024.105076

When stress invariants up to the second order are employed to construct failure criterion for brittle materials, it involves three independent terms and therefore there are three coefficients to be determined. However, there are only two conditions a...

Rational implementation of the Mohr criterion in its general form (2024)
Journal Article
Li, S. (2024). Rational implementation of the Mohr criterion in its general form. International Journal of Mechanical Sciences, 279, 109449. https://doi.org/10.1016/j.ijmecsci.2024.109449

The Mohr criterion is successfully implemented for brittle materials in its general form based on failure envelopes formulated using quadratic functions. This is probably the first time when the criterion has been made comprehensive enough and yet co... Read More about Rational implementation of the Mohr criterion in its general form.

A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy (2024)
Journal Article
Xu, M., Sitnikova, E., & Li, S. (2024). A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy. Royal Society Open Science, 11(5), Article 240205. https://doi.org/10.1098/rsos.240205

Existing failure criteria for orthotropic materials are subject to an underlying assumption which cause contradictions when applied to genuinely orthotropic materials that are significantly anisotropic in elasticity as well as in strengths. For such... Read More about A failure criterion for genuinely orthotropic materials and integration of a series of criteria for materials of different degrees of anisotropy.
