The Weak Compatibility Equations of Nonlinear Elasticity and the Insufficiency of the Hadamard Jump Condition for Non-Simply Connected Bodies

We derive the compatibility equations of L2 displacement gradients on non-simply-connected bodies. These compatibility equations are useful for non-smooth strains such as those associated with deformations of multi-phase materials. As an application of these compatibility equations, we study some configurations of different phases around a hole and show that, in general, the classical Hadamard jump condition is not a sufficient compatibility condition.

Stiffness threshold of randomly distributed carbon nanotube networks  For carbon nanotube (CNT) networks, with increasing network density, there may be sudden changes in the properties, such as the sudden change in electrical conductivity at the electrical percolation threshold.  In this paper, the change in stiffness of the CNT networks is studied and especially the existence of stiffness threshold is revealed.  Two critical network densities are found to divide the stiffness behavior into three stages: zero stiffness, bending dominated an

Curvature matters!

In a recent article in Acta Materialia ("Atom probe informed simulations of dislocation-precipitate interactions reveal the importance of local interface curvature" ) we showed how the interface curvature influences dislocation - precipitate interactions.


Two Ph.D positions are available in the field of computational modelling in the research group of Dr Parashar at the Indian Institute of Technology Roorkee. The areas of immediate interest are

1.                  Molecular dynamics based atomistic modelling of Zr-Nb alloys. PhD candidate will work on a research project sponsored by BARC.

Peptide–Graphene Interactions Enhance the Mechanical Properties of Silk Fibroin Studies reveal that biomolecules can form intriguing molecular structures with fascinating functionalities upon interaction with graphene. Then, interesting questions arise. How does silk fibroin interact with graphene? Does such interaction lead to an enhancement in its mechanical properties?

On the origins of the idea of the multiplicative decomposition of the deformation gradient

Usually the multiplicative decomposition of deformation gradient in finite plasticity is (incorrectly) attributed to Lee and Liu (1967). This short note discusses the origins of this idea, which go back to the late 1940s. We explain that the first explicit mention of this decomposition appeared a decade earlier in the work of Bilby, et al. (1957) and Kröner (1959). While writing this note I found out that Bruce Bilby passed away a couple of years ago at the age of 91.
