An equation of state for shock loaded powders [PDF]

open access: yesJournal of Applied Physics, 1991
A simple analytical model is developed for the shock Hugoniot of a powdered material. Previous models have exhibited decreasing accuracy when applied to powders and porous materials of high initial porosity. This deficiency has been avoided in the present model.

CONTROL OF LOADED POINTS OF A PARABOLIC EQUATION

open access: yesProceedings of the Institute of Mathematics and Mechanics, National Academy of Sciences of Azerbaijan
Summary: We consider a problem of optimal control of loading points and the corresponding reaction functions described by a loaded parabolic equation. Optimality conditions for control actions are obtained. The objective functional gradient formulas contained in these conditions are used in the algorithm for numerically solving the problem of ...
