Abstract:
The strain-stress state of the solid propellant rocket engines (SPRE) is simulated under impact. Orthotropic organoplastic is the material of the shell. The effect of orientation of elastic and strength properties of the shell material on the strain-stress state of the solid propellant is investigated. Normal interaction of single steel cylinder strikers and oblique impact, both simultaneous and at different times of multiple, converging steel spheric particles with SPRE are considered in the work. The investigation is conducted numerically. The numerical modeling was carried out in three-dimensional statement by a method of finite elements in frameworks of the continual approach of the mechanics of deformable solid. The destruction of the anisotropic material is described by tensor polynomial criterion of the fourth degree, which takes into account the influence of hydrostatic pressure.
