Double initial and caustic curves in diametrically compressed transparent discs - Application to the contact length

Christos Markides

General formulae for double initial and caustic curves (reflected and transmitted) are obtained in the case of smooth contact of two cylindrical elastic bodies of arbitrary radii. Namely, based on the method of reflected and transmitted…
