Title:
Conditions for guaranteed destruction and explosion resistance of beam structural elements in the event of an explosion in water
Keywords:
beam, impulse load, explosion in water, added mass, maximum bending moment, dynamic criterion of failure.
Abstracts:
According to the data of the authors’ earlier studies, the conditions of guaranteed destruction and guaranteed explosion resistance of a beam freely lying on non-deformable supports in water were found. The impulse dynamic load is created by the explosion of a concentrated charge of a condensed explosive (HE) located in water at a fixed distance from the beam. Destruction is understood as the loss of the bearing capacity of the beam due to the appearance of plastic zones (hinges), cracks, and fragmentation in it. The criterion of destruction generalized to the action of dynamic load is used, based on the achievement of critical values by the maximum bending moment.
