Laboratory Modeling of Meteorite Impact Craters by Z-pinch Plasma

Desai, et al. [1] simulated microparticle lunar impact craters using laser impacts. They produced crater diameters of several hundred μm in Al. Ford [2] made observations about lunar craters simulated by spark-machining on metal. These were also very small scale craters. This work expands the size of simulated impact craters from their sub-millimeter craters to craters over a centimeter and exp...

Peridynamic States and Constitutive Modeling

A generalization of the original peridynamic framework for solid mechanics is proposed. This generalization permits the response of a material at a point to depend collectively on the deformation of all bonds connected to the point. This extends the types of material response that can be reproduced by peridynamic theory to include an explicit dependence on such collectively determined quantitie...

Ice-associated Impact Craters on Mars: Implications from Mola Observations

Numerical Modeling of Shatter Cones Development in Impact Craters

Introduction: Shatter cones are the characteristic forms of rock fractures in impact structures. They have been used for decades as unequivocal fingerprints of meteoritic impacts on Earth [1,2]. The abundant data about shapes, apical angles, sizes and distributions of shatter cones for many terrestrial impact structures should provide insights for the determination of impact conditions and char...
