Numerical investigation for non-linear problems of explosive technologies
Applied codes to solve the problems of high velocity medium and bodies interactions were produced. Bodies may be compound geometrical shapes and various physical and mechanical properties. The finite element algorithm is based on numerical approximations of integral laws of mass, momentum and energy conservation. This algorithm is completely conservative. There were carried out numerical investigations of nonlinear problems concerned the explosive technology applications:
- multiply assemblies of frames and shells throwing by plate, cylindrical and spherical detonation waves;
- impact interactions of elastic and plastic bodies;
- underwater explosive actions оп compound constructions;
- problems of working operation optimizations for explosive divisions of the military and civil technique frames.
