TL;DR: In this article, the authors considered the Navier-Stokes equations with high-speed compressible flows with shocks in a viscous and conducting medium, with the ultimate objective of establishing the desired features of a general mathematical and computational framework for such initial value problems (IVP) in which: (a) the numerically computed solutions are in agreement with the physics of evolution described by the governing differential equations (GDEs) i.e. the IVP, (b) the solutions are admissible in the non-discretized form of the GDEs

TL;DR: In this paper, a comparison among classical elasticity, non-local elasticity and modified couple stress theories for free vibration analysis of Timoshenko beams is presented. But the results depend on the beam cross-sectional size while those of the nonlocal theory do not, and convergence of both non-classical theories to the classical theory is observed as the beam global dimension increases.

TL;DR: In this paper, the authors present numerical simulation results for the compressible Euler equations and compressible Navier-Stokes equations using least-squares finite element models for the high and low-speed compressible flow regime.

TL;DR: In this paper, the authors investigated damage mechanisms and deformation of honeycomb sandwich structures reinforced by functionally graded face plates under ballistic impact and found that the structure conformed to ballistic impact.

TL;DR: In this article, the ballistic impact response of a novel sandwich structure consisting of aluminum honeycomb and Al/SiC functionally graded face sheets was determined by a single-stage gas gun system and numerical simulations were performed using the explicit finite element code, LS-DYNA.
