Quantification of dislocation structures from anelastic deformation behaviour

Anelastic Deformation of Boron Fibers

Dislocation structures and the deformation of materials.

We present results from phase-field simulations of a two-dimensional model of dislocation microstructure development under increasing strain that incorporates the effects of the full, three-dimensional, microstructure in an approximate way. Despite its simplicity, the model yields quantitative predictions of both the deformation properties of face-centered cubic metals as well as key descriptor...

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

Experiments on deformation behaviour of functionally graded NiTi structures

Functionally graded NiTi structures benefit from the combination of the smart properties of NiTi and those of functionally graded structures. This article provides experimental data for thermomechanical deformation behaviour of microstructurally graded, compositionally graded and geometrically graded NiTi alloy components, related to the research article entitled "Functionally graded shape memo...

Anelastic Behaviour of Materials under Multi-axial Strains

A theory of anelasticity is presented, which involves the relaxation of all the elastic compliances as a function of orientation. It is shown that. in addition to the usual relaxations of Young's and shear moduli. anelastic phenomena related to the relaxation of Poisson's ratio should be considered. Finally, the theory is applied to anelastic data in Zircaloy-4 and AISI-1080 steel. obtained in ...
