Abstract
The paper describes an approach to the simulation of arbitrary laboratory tests with homogeneous stress and strain fields applicable to most constitutive models common in geomechanics. The method by Bardet and Choucair [Int.
J. Numer.

Geomech. 15(1):1-19, 1991] is generalized for an arbitrary number of controlling and controlled variables. The approach is illustrated for time-dependent thermo-hydro-mechanical constitutive models.
The purpose of the method is to define an endless variety of different laboratory tests declaratively by means of two matrices E and S, which define the constraints on the controlled quantities such as stress, strains, suction, or temperature. Copyright (C) 2016 John Wiley & Sons, Ltd.
