Wide Width Tensile Testing

Tensile testing is among the most standard tests performed by universal testing machines yet depending on how the test specimen is used in its native environment, setting up the tensile test method is not always straightforward. Wide width tensile testing is a type of tensile testing procedure used with specimens that are prepared with wider width than the standard tensile specimen coupons. This blog posts covers wide width tensile testing, standards outlining wide width testing methods, and the necessary equipment.

Modeling the Locomotion of Soft Robots using Discrete Elastic Rods

Dear Colleague,

I write to bring your attention to a recent paper describing the use of a planar version of Bergou et al.'s discrete elastic rod theory to model and simulate a prototype caterpillar-inspired soft robot. The paper just appeared in Soft Robotics:

Nanoscale self-healing mechanisms in shape memory ceramics

Shape memory ceramics, such as yttria-stabilized tetragonal zirconia (YSTZ), offer unique properties including ultra-high operating temperatures and high resistance to oxidation. However, they are susceptible to formation of defects during manufacturing and/or by mechanical deformation. To completely take advantage of their shape memory properties, it is necessary to fully understand the nano-structural evolution of defects under external stimuli. In this study, defect evolution behaviors in YSTZ nanopillars are investigated by atomistic simulations.

Competition between formation of Al2O3 and Cr2O3 in oxidation of Al0.3CoCrCuFeNi high entropy alloy: A first-principles study

We studied the oxidation behavior of face-centered cubic Al0.3CoCrCuFeNi high entropy alloy through first-principles calculations. Three surface orientations were chosen for oxidation, and all the possible combinations of atomic positions at these surfaces were considered. The adsorption energy of oxygen adhesion to the studied surfaces was the lowest for the sites with more neighboring Cr atoms, and the second most favorite site for oxygen adsorption had more neighboring Al atoms.

Phonons in chiral nanorods and nanotubes: a Cosserat rod based continuum approach

A Cosserat rod based continuum approach is presented to obtain phonon dispersion curves of flexural, torsional, longitudinal, shearing and radial breathing modes in chiral nanorods and nanotubes. Upon substituting the continuum wave form in the linearized dynamic equations of stretched and twisted Cosserat rods, we obtain analytical expression of a coefficient matrix (in terms of the rod's stiffnesses, induced axial force and twisting moment) whose eigenvalues and eigenvectors give us frequencies and mode shapes, respectively, for each of the above phonon modes.

Modeling Prophylactic Sacral Dressings with Tel Aviv University

The sacrum is the most susceptible anatomical site for developing pressure injuries (PIs), including deep tissue injuries, during supine lying. Prophylactic dressings are generally designed to reduce friction, alleviate internal tissue shear loads, manage the microclimate, and overall cushion the soft tissues subjected to sustained deformations under the sacrum.
