Like Poisson’s effect, mechanical coupling is a directional indirect response by a directional input loading. With the advance in manufacturing techniques of 3D complex geometry, architected materials with unit cells of finite volume rather than a point yield more degrees of freedom and foster exotic mechanical couplings such as axial–shear, axial–rotation, axial–bending, and axial–twisting.

1. Introduction
Biological functions in living systems are closely related to their geometries and morphologies. Toroidal structures, which widely exist in nature, present interesting features containing positive, zero, and negative Gaussian curvatures within one system. Such varying curvatures would significantly affect the growing or dehydrating morphogenesis, as observed in various intricate patterns in abundant biological structures.
The Department of Neurology, Dell Medical School, and the James T. Willerson Center for Cardiovascular Modeling and Simulation, Oden Institute, have a jointly administered opening for a Post-doctoral Fellow in the area of Neurovascular mechanics derived from clinical images.
The mission of the ASME Aerospace Structures, Structural Dynamics, and Materials (SSDM) Conference is to convene and serve the global aerospace structures, structural dynamics, and materials communities, continuing the legacy left behind by the AIAA/ASME/ASCE/AHS/ASC SDM conference. Currently, we are accepting Presentation-only Abstracts (deadline: Feb. 13). The inaugural conference will be held in San Diego (June 19-21 2023). More details can be found at https://event.asme.org/SSDM.
We developed a method enabling a single material system to transform with untethered, reversible, low-powered reprogrammable deformations and shape locking via the application of magneto-thermomechanically triggered prestress on the Shape Memory Polymers (SMPs) and structural instability with asymmetric magnetic torque. The mutual assistance of two physics concepts—magnetic control combined with the thermomechanical behavior of SMPs is demonstrated, without requiring new materials synthesis and high-power energy for reprogramming.
Here is a recent paper of our lab focusing on the physico-chemical origin of the thermoreversible properties of an organohydrogel made of polysaccharides. #greenchemistry
Dear fellow iMechanicians,
Here is our recent paper that studies and models the rheological behavior of PLA deposited by 3D printing and allows to highlight the important process parameters than enable a full healing of the interface between printed layers.
Abstract
Dear members of iMechanica, We are very pleased to announce the good health of the first overlay journal in Solid Mechanics, the so-called "Journal of Theoretical, Computational and Applied Mechanics" Journal of Theoretical, Computational and Applied Mechanics" which is a scholarly journal, provided on a Fair Open Access basis, without cost to both readers and authors. The Journal aims to select publications of the highest scientific caliber in the form of either original research or review in Solid Mechanics.
