THE DYNAMICS OF SLENDER BODIES IN DENSE MEDIA UNDER CONDITIONS OF THELOCAL INTERACTION-MODEL

Using a model of local interactions an asymptotic theory is constructe d for the plane motion of a slender sharpened body of revolution when it is fully immersed in a dense medium and there is no how separation at the lateral surface. Assuming that at the initial instant of time t he dynamic component of the normal stress is much greater than the ten sile strength, the domain of variation of the governing parameters cor responding to asymptotically stable types of motion is found for trans lational motion of a body at zero angle of attack.
