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.

Dear Colleagues,

The University of Tulsa Department of Mechanical Engineering is searching for a postdoctoral researcher to support our recently awarded a U.S. Department of Energy Solar Energy Technology project to develop novel a CSP Collector system https://www.energy.gov/eere/solar/seto-fy2018-concentrating-solar-therma... TU and collaborators will develop a new carbon-based receiver system with a bio-inspired microvascular architecture.

Enthusiastic and highly motivated postdoctoral scientists are sought to work with Dr. Kun Zhou at the School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore on the following areas:

1. Metal printing and process modeling (DED or SLM printing)

2. Polymer printing (polymer synthesis, modification and MJF/SLS printing)

We have an open PhD position starting in the Spring or Fall semester 2020 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee – Knoxville. A high quality PhD student is sought to study failure of structural materials under fatigue by developing a novel computational approach that explicitly targets traction equilibrium and displacement compatibility along the grain boundaries.

PhD Studentship: Next-Generation Fracture Modelling

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:

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.

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.

A postdoctoral research associate opening with a primary focus on atomistic simulations of defects and mechanical behaviors of Mg and Mg alloys is available in Liang Qi’s group (http://cms.engin.umich.edu/) at University of Michigan, Ann Arbor. Qi’s group is involved in the PRedictive Integrated Structural Materials Science Center (PRISMS), a DOE-BES funded research center dedicated to integrated computational and experimental studies of structural alloys located at University of Michigan.

Link to our new paper outlining some strategies to steer interfacial debonding to a desired interface during a demolding process when the two interfaces in a 3-layer structure are equally weak. The article can be downloaded for free until July 5th. Would sincerely appreciate any feedback.

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.

Applications are invited for PhD positions at the Algorithms in Medicine and Neuro-Technology Lab (AIMAN Lab) in the Department of Mechanical Engineering at George Mason University, Fairfax, VA. "Research" The AIMAN Lab pursues fundamental breakthroughs in biomedical cyber-physical systems.

There is an opening for a post-doctoral scholar in the Department of Materials Science and Engineering and the Hopkins Extreme Materials Institute at Johns Hopkins University.

As part of a collaborative project between different faculties of the University of Liege (Belgium), there is an open position to develop and validate numerical models for shape memory composite.

The main objective of the offered Post-Doc position will be to develop a numerical modeling framework for cracking in high entropy alloys

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.

Applications are invited for a post-doctoral position at the University of Pavia, Italy, with Prof. Epifanio Virga (http://matematica.unipv.it/it/people/2026). The proposed research theme is

MATHEMATICAL MODELS FOR ADVANCED SOFT MATERIALS

The call (both in Italian and English) together with the application forms (in both languages, but only one needs to be filled in) can be found at the following addresses:
