This blog concerns an interesting review of the interaction integral methodology. It deserves to be read by everyone dealing with analyses of cracks. If one's focus is on mathematical analysis or numerics is irrelevant. The review is for all of us. The review paper is, ”Interaction integral method for computation of crack parameters K–T – A review", by Hongjun Yu and Meinhard Kuna, Engineering Fracture Mechanics 249 (2021) 107722, p. 1-34.

Quite a few of mechnicians are active a Twitter. There we interact with one another, and with broad communities. Here are several mechanicians active on Twitter:

There is an immediate opening of a postdoctoral researcher in the Mechanics of Soft Materials Lab (https://www.msm.seas.ucla.edu/) in the Department of Mechanical and Aerospace Engineering at the University of California, Los Angeles (UCLA). The research will be on additive manufacturing of soft materials and soft machines. The successful candidate should have a PhD degree with expertise in experimental polymer materials.

We have two PhD positions in the area of additive manufacturing of metals and alloys. We are looking for self-motivated and enthusiastic students with a degree in mechanical or materials engineering.

Students with following backgrounds are strongly recommended to apply:

The Mechanics of Infrastructure Materials research group are looking to hire a Postdoctoral Research Associate (PDRA) to work in the prediction of hydrogen embrittlement using computational methods. The Research Associate will work under the supervision of Dr Emilio Martínez-Pañeda and the project is supported by TENARIS. 

One NSF-funded Ph.D. position is available immediately in the area of computational polymers in the group of Dr. Jihong Ma (https://sites.google.com/umn.edu/jihong-ma-group/home?authuser=0) at the University of Vermont.

dear collegues, I may be interested to share your views on an "asperity theory" modified Persson's rubber friction contact mechanics theory which I find not clearly motivated and seems to lead to erroneous conclusions ---- but I am also unable to reproduce the results claimed by the authors. The preprint is here, and the original paper attached: https://www.researchgate.net/publication/359392510

Curious to explain Earth and Sea evolution?  Have a solid physical/mathematical/mechanical/computational background? You are invited to apply for a funded MSc/PhD/Postdoc position at the Laboratory of Computational Physics in Marine Sciences

Octopus, clingfish, and larva use soft cups to attach to surfaces under water. Recently, various bioinspired cups have been engineered. However, the mechanisms of their attachment and detachment remain elusive. Using a novel microcup, fabricated by two-photon lithography, coupled with in situ pressure sensor and observation cameras, we reveal the detailed nature of its attachment/detachment under water.
