“…It must be elliptic, and its shape depends on the local values of the curvatures of the two bodies in the point of contact. Two alternatives appear to overcome this drawback; the approximation of a non-elliptic contact zone by a set of ellipses as used by Pascal & Sauvage [25], and a method based on virtual interpenetration (Kik & Piotrowsky [26,27] and Ayasse & Chollet [28,29])…”

“…As far as turnouts are concerned, the SH method has been applied by Sebès et al (2006). In VOCO, contact parameters are preprocessed in look-up tables.…”

“…An alternate method allowing non-Hertzian contact has been introduced by Kik & Piotrowski (1996) and further developed by Ayasse & Chollet (2005). This so called semi-Hertzian method (SH) has been applied by Sebès et al (2006) in the case of turnouts. In order to be coupled with FEM, it has been here necessary to slightly adapt it: this topic is addressed in section 3.…”
