Overview
The d’Alembert solution for the problem of the longitudinal collinear collision of two finite elastic plane-ended bars of the same cross section and material was solved for the first time in [1] by means of the one-dimensional wave equation, which postulates a uniform stress distribution across any section of the rods. The impact is accompanied by the generation of two transient longitudinal waves of strain which propagate in the positive and negative x-directions relative to the moving bars with the velocity \( c = \sqrt {{E/\rho }} \), where E and ρ are the elastic modulus and the density, respectively. The displacement function u was selected as the main function, which is assigned in the form
where \( \xi = x - ct \), \( \eta = x + ct \), \( f(\xi ) \),...
