Stress state of partially clamped fluid-filled spherical shell under impulse excitation (English)
0 references
The authors discuss the stress-strain state of a closed elastic spherical shell filled with an ideal compressible fluid. The excitation source is the energy brought by a pulsed injection into the gas cavity of the center of the system. Hypotheses for the solution of the problem by the finite difference method are presented and a correct mathematical statement of the problem is given. The results for stress values changing in time are obtained in both the case of free shell and the case of partial rigid fixing of the shell surface. The effect of rigid fixing on the shell stress-strain state is examined.
