Local wave theory of the collision of elastic bodies. Noncentral impact - Two-dimensional problem in the ideal-fluid approximation

An approach is developed for studying the collision of two bluff elastic bo dies. Noncentral impact is examined within the framework of a two-dimension al problem. Nonsteady mixed boundary conditions are formulated with an unde fined moving boundary. An infinite system of Volterra integral equations of the second kind is obtained for the case when the shear modulus is equal t o zero. Numerical results are presented for the case of two identical spher es.
