Joost Jacques Kalker (25 July 1933 The Hague – 24 April 2006) was a Dutch professor at Delft University of Technology, recognized for his contributions to the field of Contact mechanics.

[1] Joost J. Kalker and his family were persecuted during the German occupation of The Netherlands in World War II.

His PhD dissertation of 1967 was entitled: “On the rolling contact of two elastic bodies in the presence of dry friction”.

[2] In his thesis, Kalker proposed the mechanics behind frictional rolling with arbitrary lateral and longitudinal creep and spin.

[6] Joost J. Kalker was advisor of six PhD researches: Max Viergever (1980), Francois van Geer (1987), Juergen Jaeger (1992), Gerard Braat (1993), Frédéric Jacques Périard (1998) and Zili Li (2002).
