Universal Deformations in Anisotropic Nonlinear Elastic Solids

Universal deformations of an elastic solid are deformations that can be achieved for all possible strain-energy density functions and suitable boundary conditions. They play a central role in nonlinear elasticity and their classification has been mostly accomplished for isotropic solids following Ericksen's seminal work. Here, we address the same problem for transversely isotropic, orthotropic, and monoclinic solids.

Society of Engineering Science (SES) Annual Conference 2021

We are happy to announce the 2021 SES Meeting to be held in October. This year’s SES Meeting is an exciting departure from conventional virtual conferences. It will be organized as a Virtual Month (https://socengsci.org/ses-virtual-month/) spread over five days (October 1, 5, 15, 19, and 29). Each day will be a theme, which includes a fishbowl event, presentation, and poster session. A fishbowl is similar to a panel discussion, but with more interaction and informality.

Call for Nominations for ASME's Applied Mechanics Division Awards 2021

Dear Colleagues,

We wanted to alert you for the call for nominations of the awards of the Applied Mechanics Division (AMD) of the American Society of Mechanical Engineers (ASME), which are due on September 15th, 2021.

Failure and Fracture of Rubberlike Materials

We review some recent approaches to modeling failure and fracture of soft materials. By failure we mean the onset of damage via material instability. By fracture we mean further localization of damage into cracks with their subsequent propagation.

How to better grasp your spoon?

How can shear loading rate affect the soft adhesive contact area? A new blog post in tribonet.org discusses the problem following the paper "Papangelo, Antonio. (2021). On the Effect of Shear Loading Rate on Contact Area Shrinking in Adhesive Soft Contacts. Tribology Letters. 69." just published in Tribology Letters.

Research Fellow positions available at NTU, Singapore

We are seeking strongly motivated candidates to fill two Research Fellow positions in the Department of Mechanical and Aerospace Engineering (MAE) at Nanyang Technological University (NTU), Singapore. The successful candidate will work on experimental studies in the area of cell mechanics, bioprinting, and bio-hybrid soft robotics. We are particularly interested in candidates with research experience in bioengineering, soft materials, mechanobiology and applied mechanics.

An assessment of phase field fracture: crack initiation and growth

Dear iMechanicians,

We have contributed to the Special Issue organised by the Royal Society on occasion of the centenary of Griffith's seminal paper with a paper revisiting phase field fracture methods and their connection with conventional fracture mechanics theory. I hope that you find it of interest. (https://royalsocietypublishing.org/doi/10.1098/rsta.2021.0021)

Computing wrinkling and restabilization of stretched sheets based on a consistent finite-strain plate theory

It was reported both in experiments and computations using some classical plate theories that wrinkles can appear in a uniaxially stretched rectangular hyperelastic film with clamped-clamped boundaries and can be suppressed upon further tension. Here, based on a recently-available consistent finite-strain plate theory, we investigate this complex instability problem with isola-center bifurcation (the nontrivial solution curve begins and ends at two distinct points on the trivial line) in more depth and present an efficient numerical algorithm.
