Abstract

One hundred years of toughness

The year 2021 marks the centennial of the publication of paper, The Phenomena of Rupture and Flow in Solids, by Griffith. To fracture or to flow, that is the question. The question has been asked and answered in so many ways, which are recounted and celebrated in this Twitter thread:

Static and dynamic mechanical properties of wire and arc additively manufactured SS316L and ER70S6,

In a new paper, we report our observations of the mechanical response (quasi-static and dynamic) of woire arc additively manufactured steels. An interesting alternative to the "conventional" powder based 3D printing. The paper is temporarily available on:

Developments in Photoelasticity: A renaissance

Have you ever wondered that you can visually see the stress patterns live in a loaded structure! I am not speaking about the contours that you see in commercial finite element software #fea .

For e.g. see the colorful image attached. The fringe patterns are the live stress field around a crack in a loaded structure.

Improved oxidation resistance of high emissivity coatings on fibrous ceramic for reusable space systems

Towards the development of reusable space systems, high emissivity coatings on fibrous ceramic substrates with improved thermal resistance are needed. In this study WSi2–MoSi2–Si–SiB6-borosilicate glass coatings were prepared on fibrous ZrO2 by slurry dipping and subsequent high temperature rapid sintering. A coating with 20 wt% WSi2 and 50 wt% MoSi2 presents optimal thermal stability with only 10.06 mg/cm2 mass loss and 4.0% emissivity decrease in the wavelength regime 1.27–1.73 μm after 50 h oxidation at 1773 K. The advantages of double phase metal-silicide coatings combining WSi2 and MoSi2 include improved thermal compatibility with the substrate and an enhanced glass-mediated self-healing ability.

Misuse of Eringen's non-local elasticity theory for functionally graded materials

Nearly 50 years ago, Eringen developed a nonlocal theory of elasic solids according to which the Causchy stress tensor "sigma" at a point x depends upon the strain tensor "epsilon" not only at the point x but also at all other points in the body.  For homogeneous solids, and a few additional assumptions, he showed that the constitutive relation can be reduced to a differential form that has become popular among people studying deformations of functionally graded materials (FGMs).  However, an FGM is inhomogeneous

Statistical mechanics of a dielectric polymer chain in the force ensemble

Dear colleagues,

We invite you to see the preprint of our new paper "Statistical mechanics of a dielectric polymer chain in the force ensemble" that will appear in Journal of the Mechanics and Physics of Solids. Here we compute the electroelasticity of single polymer chains using both analytical approximations and novel MCMC techniques. Working in the fixed force ensemble facilitates the derivation of the analytical approximations, which are shown to agree well with the MCMC results. This work complements prior work on the statistical mechanics of dielectric polymers chains obtained in a different ensemble. (https://doi.org/10.1016/j.jmps.2021.104658).

Simultaneous Recovery of Transverse Stresses at all Points in a Plate

We address the challenging issue of simultaneously finding transverse shear and normal stresses at all points in a plate from a priori known values of the in-plane stresses at plate’s interior points. The principle of virtual work is employed to equate the work done by the transverse stresses to the difference between the work done by the external forces (applied surface tractions and body forces) and that by the in-plane stresses.
