We study the gravitational collapse of a self-gravitating charged scalar-field. Starting with a regular spacetime, we follow the evolution through the formation of an apparent horizon, a Cauchy horizon and a final central singularity. We find a null, weak, mass-inflation singularity along the Cauchy horizon, which is a precursor of a strong, spacelike singularity along the r = 0 hypersurface. T...

The dynamics of cavitation bubbles and their interaction with solids has been studied for long, mostly on the macro-scale sheet vortex cavitation. Erosion takes place small, concentrated areas solid walls exposed to One-way fluid structure (FSI), in which feedback material deformation is not considered, provides an adequate understanding underlying mechanism. However, practical applications mot...

Since the literature lacks an effective analysis method of collapse mechanisms and optimisation design theory for progressive resistance cable dome structure, a structural performance-based approach was proposed to improve structures in this study. First, dynamic response model structure were analysed after its members removed using Ansys LS-DYNA full equivalent load-based instantaneous unloadi...

We address the post-collapse dynamics of a self-gravitating gas of Brownian particles in D dimensions, in both canonical and microcanonical ensembles. In the canonical ensemble, the post-collapse evolution is marked by the formation of a Dirac peak with increasing mass. The density profile outside the peak evolves self-similarly with decreasing central density and increasing core radius. In the...
