1. Introduction
Because of its overwhelming pervasiveness and high-stakes impact on the mechanical performance of structures made of inorganic and live matter alike (bridges, airplanes, bones, ligaments,...), fracture has attracted the attention of humans, researchers and laymen the same, for centuries.
An elastic cloak hides a hole (or an inhomogeneity) from elastic fields. In this paper, a formulation of the optimal design of elastic cloaks based on the adjoint state method, in which the balance of linear momentum is enforced as a constraint, is presented. The design parameters are the elastic moduli of the cloak, and the objective function is a measure of the distance between the solutions in the physical and in the virtual bodies. Both the elastic medium and the cloak are assumed to be made of isotropic linear elastic materials.

Simuli-responsive hydrogels that swell under constraints such as spatial geometric confinement are commonly employed in many applications to perform mechanical work. In this contribution, we present a simple 3D-printing based method to quantify the mechanical interactions between the gels and their environment. Our findings underscore the potential of gels in the design of actuators, sensors, biomedical devices, etc…
Dear iMechanica colleagues; I am happy to share with you our recent paper that is just published in Acta Materialia, it is open access:
S. Kavousi and M. Asle Zaeem. Mechanisms of nucleation and defect growth in undercooled melt containing oxide clusters. Acta Materialia 252 (2023) 118942 (12 pages).
what are the main material properties a substrate should have if you want to be able to cut through it nicely and have a clean cut? I know a little bit about cutting tools but not much about the substrate?
A postdoctoral research position is available in Dr. Katherine Yanhang Zhang’s Multi-Scale Tissue Biomechanics Lab in the Mechanical Engineering Department at Boston University.
Dear Colleagues,
I would like to draw your attention as well as share an excellent standing-out example of an outcome of decades of focused academic research as commercial software which finds usage in several industries such as biomedical, electrical, aerospace, civil, mechanical, manufacturing, biological, and agriculture.
Dear member,
I am delighted to extend an invitation to attend the next US National Committee of Theoretical and Applied Mechanics (USNC/TAM) Distinguished Lecture to be delivered by Professor John Rogers of Northwestern University. The event will take place in-person, at the National Academies in Washington DC, and online (Zoom Live Stream) on May 5th, 2023, 5-6 PM ET. A flyer with detailed information and a link for registration is enclosed.
Dear iMechanica community,
