A mathematical model for the magnetorheological materials and magneto reheological devices
In this study, the behaviour of MR fluid has been systematically investigated within the scope of continuum mechanics. The necessary balance equations have been written for a continuous medium which takes place in the electromagnetic field.

Implicit integration scheme for porous viscoplastic potential-based constitutive equations [PDF]
This paper deals with a viscoplastic potential-based model allowing thermomechanical damage behavior modeling of porous materials. The model describes rate dependent effects, hardening, creep as well as defects coalescence and propagation.

Computational Rheology with Integral Constitutive Equations
Computational rheology deals with the formulation and solution of constitutive equations for non-Newtonian materials. From these the emphasis is put on polymeric materials, which exhibit both viscous and elastic behaviour in flow and deformation.

Review of Creep Cavitation and Rupture of Low Cr Alloy and its Weldment [PDF]
This paper presents a review of creep cavitation and rupture of low Cr alloy and its weldment, particular in the heat-affected zone (HAZ). Creep damage is one of the serious problems for the high temperature industry.

Structure and Calibration of Constitutive Equations for Granular Soils
The form of incremental constitutive equations for granular soils is discussed for the triaxial configuration. The classical elasto-plastic approach and the semi-empirical model are discussed on the basis of constitutive relations determined directly ...

Modelling, identification and application of phenomenological constitutive laws over a large strain rate and temperature range [PDF]
A review of the different phenomenological thermo-viscoplastic constitutive models often applied to forging and machining processes is presented. Several of the most common models have been identified using a large experimental database (Hor et al., 2013)

Material constitutive behaviour and microstructure study on aluminium alloys for friction stir welding [PDF]
The material constitutive behaviour and microstructure of Aluminium alloys 6082 and 7449 were studied with the Gleeble hot compression test. The novel aspect of the work is that the testing was done at high strain-rates and at temperatures within 5 K ...
