Increase in opportunities of a resonant method of destruction of an ice cover due to use of an interference of the excited flexural and gravitational waves
The possibility of increasing the resonant method of the ice cover failure through the use of interference excited by flexural-gravitational waves arising from the simultaneous motion of several amphibian hovercrafts (AHC). AHCs move over the ice cover abreast. Experimental and theoretical study the influence of the distance between loads on the stress-strain state of the ice cover. The analysis is carried out on the basis of the solution of the differential equation describing the visco-elastic oscillations of the ice cover from the action of a moving load. Solution of the equation is obtained in integral form. Experimental studies were carried out in an ice basin on a natural ice sheet.
