A thermodynamically consistent theory of stress-gradient plasticity
B. D. Reddy, P. Steinmann, A. Kergassner
As an extension to strain-gradient models of size-dependent plastic behaviour, this work proposes a model for a stress-gradient theory. The model is distinguished from earlier work…
Bounds on the elastic threshold for problems of dissipative strain-gradient plasticity
B. D. Reddy, S. Sysala
This work is concerned with the purely dissipative version of a well-established model of rate-independent strain-gradient plasticity. In the conventional theory of plasticity the…
A computational study of viscoelastic blood flow in an arteriovenous fistula
Nkosilathi Vundla, B. Daya Reddy
A finite element analysis of flows of an Oldroyd-B fluid is developed, to simulate blood flow in an arteriovenous fistula. The model uses a combination of a standard conforming fin…
Convergence in the incompressible limit of new discontinuous Galerkin methods with general quadrilateral and hexahedral elements
Beverley J. Grieshaber, Andrew T. McBride, B. Daya Reddy
Standard low-order finite elements, which perform well for problems involving compressible elastic materials, are known to under-perform when nearly incompressible materials are in…
Development of a patient-specific finite element model of the Transcatheter Aortic Valve Implantation (TAVI) procedure
Mehdi Shirzadi, B. Daya Reddy, Harish Appa
This work reports on a study to develop a patient-specific finite element model of the Transcatheter Aortic Valve Implantation procedure, using a model of a balloon-expandable perc…
Numerical Investigations of Strain-Gradient Plasticity with Reference to Non-Homogeneous Deformations
Nothando Mhlongo, B Daya Reddy
In this work, a higher-order irrotational strain gradient plasticity theory is studied in the small strain regime. A detailed numerical study is based on the problem of simple shea…
