The focus of this paper is on structural changes, sometimes accompanied by composition changes, that develop adjacent to sliding interfaces in ductile materials. Examples of observations on sliding of crystalline and non-crystalline materials are com

Scientists and engineers still debate the relative contributions of roughness and interlocking of asperities, adhesion and interatomic forces, and elastic and plastic deformation in friction phenomena. However a central point of agreement does exist:

Hydro code implementations of ejecta dynamics at shocked interfaces presume a source distribution function of particulate masses and velocities, f0(m,u;t). Some properties of this source distribution function have been determined from Taylor- and sup

The authors have investigated the acceleration of very thick cylindrical aluminum liners using the Pegasus II capacitor bank. These accelerated solid liners will be used to impact other objects at velocities below 1.5 km/sec, allowing them to generat

The linear combination of atomic orbitals method is applied to clusters of 365 atoms, which are constructed to model the pair distribution functions of liquid and amorphous Fe. From these models the authors compute densities of states, spectral funct

The conductivities of liquid La and several liquid transition metals are evaluated numerically for clusters of 365 atoms. These metals are characterized by strong scattering and s-d hybridization, hence the applicability of the Boltzmann equation is
