Crater size estimates for large-body terrestrial impact [PDF]

Calculating the effects of impacts leading to global catastrophes requires knowledge of the impact process at very large size scales. This information cannot be obtained directly but must be inferred from subscale physical simulations, numerical ...

Theoretical Research Progress in High-Velocity/Hypervelocity Impact on Semi-Infinite Targets

Shock and Vibration, 2015
With the hypervelocity kinetic weapon and hypersonic cruise missiles research projects being carried out, the damage mechanism for high-velocity/hypervelocity projectile impact on semi-infinite targets has become the research keystone in impact dynamics.

Melt production in large-scale impact events: Calculations of impact-melt volumes and crater scaling [PDF]

Along with an apparent convergence in estimates of impact-melt volumes produced during planetary impact events, intensive efforts at deriving scaling relationships for crater dimensions have also yielded results.

Effect of impact angle on central-peak/peak-ring formation and crater collapse on Venus [PDF]

Although asymmetry in ejecta patterns and craters shape-in-plan are commonly cited as diagnostic features of impact angle, the early-time transfer of energy from impactor to target also creates distinctive asymmetries in crater profile with the greatest ...

Microbial mats of the Tswaing impact crater: results of a South African exobiology expedition and implications for the search for biological molecules on Mars [PDF]

, 2001
We describe microbial mats from the Tswaing impact crater in South Africa. The mats provide insights into the unique biological characteristics of impact craters and can help strategies for the search for biomolecules on ...

Experimental Impacts into Strength-Layered Targets: Ejecta Kinematics [PDF]

AImpact cratering has dominated the evolution and modification of planetary surfaces through-out the history of the solar system. Impact craters can serve as probes to understanding the details of a planetary subsurface; for example, Oberbeck and Quaide,
