Summary

 

Overview

RESEARCH Interests

 

The interaction of solutes with dislocations in engineering problems such as delayed hydride cracking (Zr alloys, nuclear industry) and stress assisted grain boundary oxidation (Ti alloys, aerospace industry). 

Size effects in crystalline materials (e.g. grain-size effects, single crystal specimen effects as in micro-pillars, micro-cantilevers and thin films).

The theory of acoustic metamaterials. 

Dislocation mechanics of the Portevin-Le Chatelier effect. 

Atomistic modelling of dislocations moving at high speeds (mobility laws and the sound barrier). 

Elastodynamics discrete dislocation plasticity of high rate problems, including shock loading, fast crack propagation and adiabatic shear banding. 

Dislocation mechanics of dwell fatigue and the dwell debit of Ti alloys used in aerospace applications.

Multiscaling methods for coupling discrete dislocation plasticity to crystal plasticity, applied to problems on indentation and fretting fatigue. 

The development of semi-analytical methods for predicting general-path crack propagation (for polycrystalline diamond, cutting tools industry). 

Virtual grain structure generation and crystal plasticity finite element analysis applied to size effects in single crystals and in metal forming applications. 

Environmentally assisted delamination of multi-layer artist paints and conservation objects with thin coatings. 

The mechanics of powder forging, and warm and high temperature metal forming technologies including lightweight gears. 

Mechanics of degradation and failure of thermal and environmental barrier coatings. 

Mechanics of metal foams and lattice materials. 

Experimental methods for in-situ characterisation of necking, the determination of dislocation mobility laws from micro-pillar compression, and fracture toughness from pillar fracture. 

Damage in metals under hot rolling conditions. 

Graded microstructure generation for efficacious material property distributions in sheet forming.

Dr. Balint heads the Materials Modelling research effort within the Metal Forming and Materials Modelling research group and is a member of the Structural Integrity research group. He is also an academic staff member of the Centre for Doctoral Training in Theory and Simulation of Materials, the Thomas Young Centre for Theory and Simulation of Materials, the Centre for Doctoral Training in Nuclear Energy, the Centre for Doctoral Training in Diamond Science and Technology, the Centre for Computational Methods in Science and Engineering, the AVIC Centre for Structural Design and Manufacture, the AVIC Centre for Materials Characterisation, Processing and Modelling and the UK Centre for Advanced Structural Ceramics.

There may be vacancies for Ph.D. students in the general areas of theoretical and computational solid mechanics, materials modelling and metal forming (see above for more detail on research areas). Candidates should ideally be eligible for EPSRC funding, which would cover tuition fees and living expenses. Self-funded students are also very welcome. Funding may be available for exceptional overseas candidates.

Further, EPSRC-eligible candidates could also consider applying to study in one of the Centres for Doctoral Training (see above).
