# J. F. Besseling

Johannes Ferdinand "Hans" Besseling (10 March 1928 – 9 May 2015) was professor emeritus of Engineering Mechanics at the Delft University of Technology, worked in the field of the application of solid mechanics to the analysis of structures; constitutive equations for the mathematical description of material behaviour. His specialities are finite element methods, continuum thermodynamics, creep and plasticity of metals.
