A new method of sheet rolling in helicoid rollers is considered. In this approach, the roller barrel is formed by a helicoid with rounded projecting tips. The effectiveness of the rollers is demonstrated, and their geometric parameters are determined

We have studied the formation of hot spot in materials under high-speed loading using the method of molecular dynamics. It is shown that the appearance of hot spots is associated with release of the elastic energy accumulated in the deficient region.

The spalling fracture in a copper crystallite with a specific intergrain boundary under pulsed loading is modeled numerically. It is found that the grain boundary changes the parameters of nonlinear waves generated by loading and significantly affect

The process of pulse-train-induced cleavage fracture in a copper crystal with grain boundary was studied by methods of computer simulation. It is demonstrated that trains of isolated compression pulses induced in the material favor the tendency to fr

The molecular-dynamic modeling of the behavior of a three-dimensional crystallite that contains a specific-type grain boundary under shear loading is performed. It is found that the accommodation of displacements of the material grains can be realize

Generation of nonlinear solitary waves in a system described by many-body interatomic interaction potentials is modeled for the first time. The behavior of a free surface of Ni and Al crystallites under high-rate loading is studied. Calculations show

An analysis is made of some characteristic features of the interaction between solitary pulses (soliton-like waves) generated under high-velocity loading and structural defects in an Al crystallite. Calculations are made using the molecular dynamics

A molecular dynamics method was used to study the interaction of isolated compression pulses with the (100) and (110) free surface in a copper monocrystallite. It is shown that this may be accompanied by cleavage fracture. Parameters of compression p
