RA in Mechanics of Li Ion Batteries - Cambridge University
Lithium ion batteries with solid state electrolytes are prone to degradation by a range of mechanisms including dendrite formation, void formation and swell-induced fatigue and micro-cracking. The topology of the battery plays a role over a number of length scales, from macro scale geometry of battery to the microstructural scale of the cathode. The kinetics of plating and stripping of lithium at free surfaces play a major role, along with the role of topology in terms of both performance and failure mechanisms.
On the Direct and Reverse Multiplicative Decompositions of Deformation Gradient in Nonlinear Anisotropic Anelasticity
In this paper we discuss nonlinear anisotropic anelasticity formulated based on the two multiplicative decompositions F=FeFa and F=FaFe.
Griffith-based analysis of crack initiation location in a Brazilian test
Dear iMechanicians, I hope that the paper below is of interest, given the wide use this experiment. Essentially, we use the generalised Griffith criterion to determine the crack initiation location in the Brazilian split test, establishing the conditions (jaws geometry and material properties) that lead to a valid test. We find that the range of conditions where the Brazilian test is valid is much narrower than previously thought, with current standards being inappropriate for a wide range of rock-like materials.

Article: Modal added-mass matrix of an elongated flexible cylinder immersed in a narrow annular fluid, considering various boundary conditions. New theoretical results and numerical validation
This paper considers the fluid–structure interaction problem of two coaxial cylinders separated by a thin layer of fluid. The flexible inner cylinder is imposed a small amplitude harmonic displacement corresponding to a dry vibration mode of an Euler–Bernoulli beam, while the external cylinder is rigid. A new theoretical formulation based on the assumption of a narrow fluid annulus is derived to estimate the modal added-mass matrix of the vibrating cylinder.
Production of Fibres from Lunar Soil: Feasibility, Applicability and Future Perspectives
The construction of a lunar base is considered to be an important step towards deep-space exploration by humanity, and will rely on the utilisation of in situ lunar resources. In this paper, we discuss the current knowledge on the feasibility of converting lunar soil to high-performance fibres that can be used for the construction of a lunar base. This fibre would be combined with further portions of lunar soil to generate fibre-reinforced composites, which is utilized as multi-functional materials for lunar base construction.
