I strongly recommend reading these two papers about the recent loss of Ken L Johnson, FRS, Timoshenko Medallist, Gold Tribology Medal, who died the day of my 45th birthday, exactly twice as old.

A majority of dielectric elastomers (DE) developed so far have more or less viscoelastic properties. Understanding the dynamic behaviors of DE is crucial for devices where inertial effects can not be neglected. Through construction of a dissipation function, we applied the Lagrange’s method and theory of non-equilibrium thermodynamics of DE and formulated a physics-based approach for dynamics of viscoelastic DE. We revisited the nonlinear oscillation of DE balloons and proposed a combined shooting and arc-length continuation method to solve the highly nonlinear equations.
Our group has one postdoctoral position opening supported by Singapore University of Technology and Design (SUTD)-Digital Manufacturing and Design Centre (DManD) for a project involving multimaterial stereolithography for 3D/4D printing.
We are seeking self-motivated postdoctoral researchers with a PhD degree in mechanical engineering, mechatronics, electronic engineering orrelated fields.
I wonder if anyone in Imechanica follows or deals with Damage Tolerance of Aircraft Structures. Not having to deal with everyday certification nor having direct experience, I know only what is reported in academic books, but I am confused about what is the standard in industry and certification, assuming there is one!

A general framework is presented to model coupled thermo-elasto-plastic deformations in the theory of special Cosserat rods. The use of the one-dimensional form of the energy balance in conjunction with the one-dimensional entropy balance allows us to obtain an additional equation for the evolution of a temperature-like one-dimensional field variable together with constitutive relations for this theory. Reduction to the case of thermoelasticity leads us to the well known nonlinear theory of thermoelasticity for special Cosserat rods.
