Poking/pressurizing thin elastic sheets with sliding boundaries

Dear iMechanicians, I would like to share our recent work on the poking and bulging of elastic thin sheets that were inspired by the classical indentation test and bulge test. Under clamped boundaries, there have been well-established theories and well-controlled experiments in this field.

The poker-chip experiments of Gent and Lindley (1959) explained

Despite being commonly credited with initiating the field of cavitation in elastomers, the famed poker-chip experiments of Gent and Lindley (1959) have yet to be fully explained. One likely reason for their elusiveness is that it had long been presumed that cavitation in elastomers was a phenomenon that could be explained solely on the basis of the elasticity of the elastomer at hand.

PhD Candidate required in Computational fracture mechanics

I am looking for a PhD candidate who will be sponsered by my Institute to work in the area of fracture mechanics. 

ABAQUS experience would be an advantage and concepts in fracture mechanics and finite elements will be desirable.

If you are interested to work in this area at Indian Institute of Technology Ropar in Metallurgical and Materials Engg. department, please dont hesitate to contact me at abhishek.tiwari@iitrpr.ac.in

The candidate should be an Indian citizen.

Analysis of a model of field crack mechanics for brittle materials

Léo Morin       Amit Acharya

A computational model for arbitrary brittle crack propagation, in a fault-like layer within a 3-d
elastic domain, and its associated quasi-static and dynamic fields is developed and analyzed. It
uses an FFT-based solver for the balance of linear momentum and a Godunov-type projection-evolution
method for the crack evolution equation. As applications, we explore the questions of equilibria
and irreversibility for crack propagation with and without surface energy, existence of strength
and toughness criteria, crack propagation under quasi-static and dynamic conditions,
including Modes I, II and III, as well as multiaxial compressive loadings.
