Algorithm of Calculation of Contact Boundaries Taking Into Account the Erosion of Finite Elements at High-Velocity Interaction of Bodies

Numerical simulation of the interaction of elements of active protection with metal barriers

“…Materials behavior is described using elasto-plastic model [4][5][6][7]. Intensity limit of plastic deformations is accepted as a local criterion of shear fracture [7].…”

“…Intensity limit of plastic deformations is accepted as a local criterion of shear fracture [7]. Simulation is conducted by finite element method, it is three-dimensional and author's program software is used which allows describing fragmentation of interacting bodies [7,8].…”

Simulation of interaction of damage agents of different shape with shaped-charge munition

“…Intensity limit of plastic deformations is accepted as a local criterion of shear fracture [7]. Simulation is conducted by finite element method, it is threedimensional and author's program software is used which allows describing fragmentation of interacting bodies [7][8]. Figure 2 shows in section areas of interaction of projectiles with the shell after its penetration (for the initial velocity of 800 m/s).…”

Numerical Simulation of the Reinforced Concrete Barrier Destruction at Impact

“…Generally, the existing program software use algorithms "element-node" and "node-node" to define the possible penetration of one body into another. The given work suggests the algorithm of "element-element" type [6], proved oneself to be appropriate while solving the three dimensional objectives and enabling to use possibilities of parallel computing to a maximum extent.…”
