Abstract Rayleigh–Taylor instability (RTI) of finite-thickness shell significantly impacts shell deformation and material mixing processes, with crucial implications for inertial confinement fusion (ICF). This study focuses on the RTI growth at the dual interfaces of a thin shell. A second-order weakly nonlinear (WN) analytical theory is developed to investigate the nonlinear deformation of the shell induced by different perturbation wavelengths initially imposed at the upper and lower interfaces. The validity of the theoretical results within the WN regime has been confirmed via two-dimensional Eulerian numerical simulations. Due to the interface coupling effect, the initially imposed single-mode perturbations at the upper and lower interfaces progressively evolve, exhibiting characteristics typical of multi-mode perturbations. When the initial perturbation wavelengths differ significantly, the primary structure of RTI retains its integrity, a behavior attributed to the dominance of long-wavelength perturbations. For comparable initial wavelengths, mode-coupling significantly distorts the bubble-spike structure in RTI, with the thin shell becoming prone to rupture due to enhanced nonlinear interactions.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
