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.
Find more answers on how to interpret these images using state of the art image processing technology in the newly published book:
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.

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 inhomogene
A most readworthy paper, "Static and dynamic mode I fracture toughness of rigid PUR foams under room and cryogenic temperatures" by E. Linul, L. Marşavina, C. Vălean, R. Bănică, Engineering Fracture Mechanics, 225, 15 February 2020, 106274, 1-10, is selected for this ESIS blog. It has received a lot of attention and was for an extended period of time one of the most read papers in EFM.
The Departments of Civil and Environmental Engineering, Mechanical Engineering, and Engineering Science and Applied Mathematics at Northwestern University invite applications for the newly established Jan and Marcia Achenbach Professorship (full professor), with particular focus on candidates who are world leaders in mechanics.
Postdoctoral research associate positions are available in the Mechanical Engineering, Aerospace Engineering, and Physics Departments at the University of Michigan, Ann Arbor. The postdoctoral researchers will work with Professors Serife Tol, Ellen Arruda, Xiaoming Mao, and Anthony Waas on a new project sponsored by DARPA. These postdoctoral researchers will be collectively mentored by the aforementioned faculty members on the team.
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).
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.
