Impacting an asteroid with a spacecraft traveling at high speed delivers an impulsive change
in velocity to the body. In certain circumstances, this strategy could be used to deflect a …

We present a formulation of smoothed particle hydrodynamics (SPH) that utilizes a first-order
consistent reproducing kernel, a smoothing function that exactly interpolates linear fields …

Abstract The Double Asteroid Redirection Test (DART) is a NASA-sponsored mission that
will be the first direct test of the kinetic impactor technique for planetary defense. The DART …

Though rare, asteroid impacts are inevitable, and with the current state of technology, kinetic
impactors are the preferred but not the complete solution. If the time to impact is short, or the …

Abstract The Double Asteroid Redirection Test (DART) is a NASA mission concept currently
in Phase-A study, which will provide the first full-scale test of a kinetic impactor deflection …

We present results from a suite of 169 hydrocode simulations of collisions between
planetary bodies with radii from 100 to 1000 km. The simulation data are used to derive a …

Diverting hazardous small bodies on impact trajectories with the Earth can in some
circumstances be impossible without risking disrupting them. Disruption is a much more …

As a complement to experimental and theoretical approaches, numerical modeling has
become an important component to study asteroid collisions and impact processes. In the …

We describe a modified form of smoothed particle hydrodynamics (SPH) in which the
specific thermal energy equation is based on a compatibly differenced formalism …

This paper presents a meshless method for the modeling of shell‐type structures in fast
dynamics. The model is based on the Mindlin–Reissner theory and takes into account …
