Study on the Transient Responses of Composite Lining Tunnels Subjected to Blasting P-Waves and SV-Waves

Applied Sciences
Grounded in the principles of wave dynamics, this study employs the wave function expansion approach to mathematically describe how plane P- and SV-waves scatter around a composite tunnel lining embedded in an unbounded medium. To establish the transient

Design and Mechanical Properties of Maximum Bulk Modulus Microstructures Based on a Smooth Topology with Grid Point Density

Aerospace
The aim of topology optimisation is to determine the optimal distribution of material phases within the periodic cells of a microstructure. In this paper, the density of grid points under element volume fraction is constructed to replace the finite ...

The White Dwarf Initial–Final Mass Relation from Open Clusters in Gaia DR3

The Astrophysical Journal
The initial–final mass relation (IFMR) links a star’s birth mass to the mass of its white dwarf (WD) remnant, providing key constraints on stellar evolution.

Reduced Total Energy Requirements for the Natario Warp Drive Spacetime using Heaviside Step Functions as Analytical Shape Functions

, 2012
Warp Drives are solutions of the Einstein Field Equations that allows superluminal travel within the framework of General Relativity. There are at the present moment two known solutions: The Alcubierre warp drive discovered in $1994$ and the Natario warp drive discovered in $2001$.

An Improved Fit to the Density Fluctuations in Supersonic Isothermal Turbulence

The Astrophysical Journal
The density distribution of supersonic isothermal turbulence plays a critical role in many astrophysical systems. It is commonly approximated by a log-normal distribution with a variance of ${\sigma }_{s,{\rm{V}}}^{2}\approx \mathrm{ln}(1+{b}^{2}{M}_ ...
