| Abstract: | ased on the cubical B-spline collocation method, shock spectrs of products packaging with cubical nonlinearity under rectangular wave shock were obtained and then the effects of stiff nonlinearity,flexible nonlinearity and excitationamplitade on damaged bounds were discussed.The method of describing safety district of products packaging with cubical nonlinearity by damaged bounds curve surface was presented and then the related damaged bounds curve surfaces were given. |
