GENERALIZED METHOD FOR INVESTIGATING THE EFFECTS OF AN EXPLOSION ON BEAM STRUCTURES IN WATER
The synthesis of the energy method and the method using the equation of beam motion under the action of an explosion is considered. The results of this approach allow us to find with greater confidence the conditions for guaranteed destruction of the beam by an explosive load. the solution of the problem of beam deformation in an elastic nonlinear mode with finite deflections under the action of an explosion of a condensed explosive charge in water is obtained. The optimal shape of the elastic line is found when the beam is deformed at any time, which makes it possible to formulate the dynamic failure criterion with greater confidence and find the appropriate conditions for structural failure.
