Constitutive Modelling
Research on constitutive modelling has mainly been undertaken within the Hyperplasticity framework. Hyperplasticity is an approach based on thermodynamics, where the entire constitutive behaviour is derived from two scalar potentials. The theory takes its roots in the work of Ziegler ("An Introduction to Thermomechanics", 1976), and was developed by G. T. Houlsby, in collaboration with A. M. Puzrin and I. F. Collins among others.
Recent research contributions focusing on constitutive modelling for offshore application include:
