The attached tutorial paper is yet unpublished but I am posting a pre-print since several students I know have found it to be a useful pedagogical resource. You may also access the document on arXiv.

Here is the abstract.

Dear Colleagues,

My group at Peking University proposed a novel mechano-chemical continuum model based on the framework of thermodynamics that can describe the microstructural evolution in metallic glass, and connect it with the macroscopic plastic deformation. The model successfully simulated the shear band instability and dilatancy effects of metallic glass under uniaxial tension and simple shear.

Dear colleagues,

We have published a progress report on hydraulically amplified self-healing electrostatic (HASEL) artificial muscles in Advanced Materials. In this progress report we report the recent developments of HASEL actuators—including materials, designs, fabrication, and control—and discuss many opportunities for future research.

Dear Colleagues, 

 We cordially invite you to participate in an event of ASME Technical Committee on Mechanics of Soft Materials 2020. The detailed agenda is enclosed.

An all-natural bioinspired structural material for plastic replacement, Guan, Yang, Han, Ling, Yu, Nature Communications, 2020

Novelty/impact/significance:

A strong (stiffness 20 GPa and strength 281 MPa), tough (11.5 MPa m1/2), lightweight (1.7 g/cm3), and thermal-resistant (thermal expansion coefficient 7x10-6K-1) composite material is created, using all-natural raw materials through a mass-producible method.

PhD position(s) is available immediately in the Engineering Mechanics program in Aerospace Engineering Department at Iowa State University to perform theoretical and computational part of work on NSF-funded projects on the interaction between phase transformations and plasticity. Phase-field, micromechanical, and macroscale simulations using FEM are of interest, in close collaboration with high-pressure experiments performed in our lab. Please send vita to Prof. Valery Levitas ( vlevitas@iastate.edu ).

Cortical folding—the process of forming the characteristic gyri (hills) and sulci (valleys) of the cortex—is a highly dynamic process that results from the interaction between gene expression, cellular mechanisms, and mechanical forces. Like many other cells, neurons are sensitive to their mechanical environment. Because of this, cortical growth may not happen uniformly throughout gyri and sulci after the onset of cortical folding, which is accompanied by patterns of tension and compression in the surrounding tissue.

Postdoc position available on Mechanics/Tribology and/or Triboelectric Nanogenerators at the University of Glasgow's James Watt School of Engineering. Applicants with background in mechanics, tribology or triboelectric nanogenerators (including device fabrication and testing) are welcome. Closing date: 08-Dec-2020

In this note, we develop simple analytical formulas to estimate the effect of residual stresses on the pulse wave velocity in blood vessels. We combine these formulas with three constitutive models of the arterial wall: the Fung model and two models accounting for the dispersion of collagen fibers via 8 and 16 structure tensors accordingly. The residual stresses come into play with a description of the initial kinematics - the opening angle.
