Failure of brittle materials using simple experiments- Part 2

Here is my second video, where I tried to explain the concepts of stress state, principal stresses, Mohr circle and failure theories in layman's language and associated these concepts to explain the failure of a brittle material. This is an educational outreach initiative mainly targeted at the undergraduates (mechanical/civil/aerospace and materials engineering) studying mechanics and also other me

Instabilities in confined elastic layers under tension: Fringe, fingering and cavitation

Under tension, confined elastic layers can exhibit various modes of mechanical instabilities, including cavitation, fingering and fringe instabilities. While the cavitation has been extensively studied, the fingering and fringe instabilities have not been well understood, and the relations and interactions of these instabilities have not been explored yet. In this paper, we systematically study the formation, transition, interaction and co-existence of mechanical instabilities in confined elastic layers under tension.

Snaking elastic rods

How can an elastic rod model snake motion?

An elastic rod constrained in a perfectly smooth and rigid channel can move through a release of elastic energy and the development of a configurational force.

Post Doc in Mechanics of Polymer Foaming

Polymers are commonly foamed in the solid phase by the expansion of a dissolved gas such as CO2.  The foaming process is sensitive to the constitutive properties of the polymer, and the final porosity is dictated by bursting of the cell walls.  There is a need to model the solid foaming process for a range of polymers in order to determine the sensitivity of foaming to the properties of the polymer and to the process variables (such as thermal history and CO2 content). The foam expansion response is sensitive to the constitutive properties of the polymer.

the new impact factor for JAM

The 2016 impact factor for Journal of Applied Mechanics has increased to 2.133.  This increase is mainly due to the rapid review process, which has led to significant increase of submissions (and significant decrease of the acceptance rate).  The average time for the first round of review is < 10 days, and that for the second round of review (if necessary), including both the authors' revision time and reviewers' re-review time, is < 3 weeks.

Recent Work "Modeling the Energy Storage and Structural Evolution during Finite Viscoplastic Deformation of Glassy Polymers"

The enthalpic response of amorphous polymers depends strongly on their thermal and deformation history. Annealing just below the glass transition temperature (Tg) causes a large endothermic overshoot of the isobaric heat capacity at Tg as measured by differential scanning calorimetry, while plastic deformation (cold work) can erase this overshoot and create an exothermic undershoot. This indicates that a strong coupling exists between the polymer structure, thermal response and mechanical deformation.

Post-Doc position within the International Research Training Group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” (DFG GRK 2078)

The international research training group "Integrated Engineering of continuous-discontinuous long fiber reinforced polymer structures” offers one post-doc position at Karlsruhe Institute of Technology (KIT). Discontinuous long fiber reinforced polymer structures with local continuous fiber reinforcements represent an important class of lightweight materials. This class of materials has a significant potential for energy savings due to the high specific stiffness and strength as well as the variety of design options in diverse technical applications, e.g., in vehicle construction.
