Mechanics to explain tsunamis---Rosakis and co-workers in PNAS

Ares Rosakis and collaborators across three other institute have just published a fascinating account of a rather unexpected mechanism for generating  tsunamis. The paper, published in PNAS, is attached with this post.

The associated press-release provides a compelling lay-person summary: https://www.caltech.edu/about/news/contrary-to-previous-belief-strike-sl...

On Nye's Lattice Curvature Tensor

We revisit Nye's lattice curvature tensor in the light of Cartan's moving frames. Nye's definition of lattice curvature is based on the assumption that the dislocated body is stress-free, and therefore, it makes sense only for zero-stress (impotent) dislocation distributions. Motivated by the works of Bilby and others, Nye's construction is extended to arbitrary dislocation distributions. We provide a material definition of the lattice curvature in the form of a triplet of vectors, that are obtained from the material covariant derivative of the lattice frame along its integral curves.

Elastodynamic Transformation Cloaking for Non-Centrosymmetric Gradient Solids

In this paper we investigate the possibility of elastodynamic transformation cloaking in bodies made of non-centrosymmetric gradient solids. The goal of transformation cloaking is to hide a hole from elastic disturbances in the sense that the mechanical response of a homogeneous and isotropic body with a hole covered by a cloak would be identical to that of the corresponding homogeneous and isotropic body outside the cloak.

Writing tips

To students and junior researchers,

Together with Stephane Bordas (Luxembourg University) and Alban de Vaucorbeil (Deakin University, Australia), we have assembled a PDF (https://imechanica.org/files/how-to-write-paper.pdf) outlining our our approach to writing articles on the field of computational mechanics. Also discussed are softwares used. We hope that it will be of help to students and junior researchers.

Nonlinear statistical mechanics drives intrinsic electrostriction and volumetric torque in polymer networks

Dear colleagues,

We invite you to see the preprint of our new paper "Nonlinear statistical mechanics drives intrinsic electrostriction and volumetric torque in polymer networks" that will appear in Physical Review E. Here we use a nonlinear statistical mechanics approach to the electroelasticity of dielectric polymer chains and obtain a two-way coupling between chain deformation and dielectric response. This two-way coupling leads to electrically induced stresses and volumetric torques within an elastomer network which can be leveraged to develop higher efficiency soft actuators, electroactive materials, and novel electromechanical mechanisms. (https://doi.org/10.1103/PhysRevE.103.042504).
