Numerical methods to estimate material properties usually involve analysis of a representative volume element (RVE) or unit cell (UC). The representative volume element (RVE) or unit cell (UC) is the smallest volume over which a measurement can be ma...

The Maximum Stress Failure Criterion and the Maximum Strain Failure Criterion: Their Unification and Rationalization (2020)
Journal Article
Li, S. (2020). The Maximum Stress Failure Criterion and the Maximum Strain Failure Criterion: Their Unification and Rationalization. Journal of Composites Science, 4(4), Article 157. https://doi.org/10.3390/jcs4040157

The maximum strain failure criterion is unified with the maximum stress failure criterion, after exploring the implications of two considerations responsible for this: (1) the failure strains for the direct strain components employed in the maximum s...

A reflection on the Mohr failure criterion (2020)
Journal Article
Li, S. (2020). A reflection on the Mohr failure criterion. Mechanics of Materials, 148, https://doi.org/10.1016/j.mechmat.2020.103442

The Mohr failure criterion has been reexamined and represented in a rational manner in the context of brittle materials. The generic assumptions and their logical inferences have been elaborated, as well as the basic assumption of the isotropy of the... Read More about A reflection on the Mohr failure criterion.

Unification and parameterisation of 2D and 3D weaves and the formulation of a unit cell for composites made of such preforms (2020)
Journal Article
Xu, M., Sitnikova, E., & Li, S. (2020). Unification and parameterisation of 2D and 3D weaves and the formulation of a unit cell for composites made of such preforms. Composites Part A: Applied Science and Manufacturing, 133, https://doi.org/10.1016/j.compositesa.2020.105868

In this paper, the method to unify the definition of woven architectures in textile composites over a wide range of variations has been established. This was achieved via parametrisation of the weaves, which was conducted employing a limited set of c...

Closed-Form Solution for Secondary Perturbation Displacement in Finite-Element-Implemented Koiter’s Theory (2020)
Journal Article
Yan, J., & Li, S. (2020). Closed-Form Solution for Secondary Perturbation Displacement in Finite-Element-Implemented Koiter’s Theory. AIAA Journal, 58(4), 1-12. https://doi.org/10.2514/1.j058941

The finite-element-implemented Koiter’s initial postbuckling analysis has not managed to convince commercial finite element code developers to incorporate it into their codes to benefit structural designers and analysts. Three key obstacles have been... Read More about Closed-Form Solution for Secondary Perturbation Displacement in Finite-Element-Implemented Koiter’s Theory.
