| Abstract: | The nonlinear finite element numerical simulation software named ANSYS/LS-DYNA was adopted by dynamic simulation of blast and impact on shielding structure underwater, to analyze effects of different shielding structure to shockwave underwater. Its control equation of numerical simulation includes six kinds: particle movement, momentum conservation, quality conservation, energy conservation, constitutive model and state equation. The method of liquid-solid coupling was used to calculate the effect of explosive to structure, taking examples for steel plate, steel-aluminum plate, steel-rubber plate etc. The result indicates that the adopted physical model and numerical algorithm are more reasonable. |
