Global Composites Experts Webinar Series

Submitted by Wenbin Yu on

Composites Design and Manufacturing HUB (cdmHUB) invites you to attend the Global Composites Experts Webinar series. The goal of the series is to accumulate the vast knowledge of composites that has been developed over the past 50 years and to make it available to the global composites community. The inaugural lecture entitled Digital Disruption of Composites Manufacturing and Design will be given by Prof. Anoush Poursartip on September 3rd 11am-12pm EDT. Please visit https://lnkd.in/g9mkRjk for more details.

Experimental study of Magneto-active polymers : A Comprehensive Review

Submitted by mokarram76 on

Magnetorheological elastomers (MREs) are a class of recently emerged smart materials whose moduli are largely influenced when exposed to an external magnetic field. The MREs are particulate composites, where micro-sized magnetic particles are dispersed inside a non-magnetic polymeric matrix. These elastomers are known for changing their mechanical and rheological properties in the presence of a magnetic field. This change in properties is widely known as the magnetorheological (MR) effect.

A phase field model for elastic-gradient-plastic solids undergoing hydrogen embrittlement

Submitted by Emilio Martíne… on

Dear iMechanicians,

I hope some of you find our recent JMPS paper interesting. We combine phase field fracture, hydrogen transport and strain gradient plasticity to provide a modern rationale to the mechanism of hydrogen enhanced decohesion.

Choose a channel featured in the header of iMechanica

I have the following questions.

  1. How to model alloy in LAMMPS? How to automatically randomize the position of atoms of various types?
  2. Also how to evaluate the mechanical properties such as Elastic modulus and Fracture toughness?
  3. Is it possible to model interface fracture using LAMMPS?

Additive Manufacturing and the COVID-19 challenges: An in-depth study

Submitted by mokarram76 on

The COVID-19 pandemic created huge demand of relevant medical  and personal protective equipment (PPE) and put unprecedented pressure on the healthcare system within a very short span of time. Moreover, the supply chains system faced extreme disruptions as a result of the frequent and severe lockdowns across the globe. In this situation, additive manufacturing (AM) becomes a supplementary  manufacturing process to meet the explosive demands and ease the health disaster worldwide.

Inflation induced twist in geometrically incompatible isotropic tubes

Submitted by emuna on

We propose a new layered configuration of isotropic tubes that twists upon inflation, based on the concept of geometric incompatibilities. For more details click "Read more" below. The full paper can be found at: https://doi.org/10.1115/1.4047980.

 

Revisit initiation of localized plastic deformation: Shear band & necking

Submitted by Lixiang Yang on

Hello Dear All,

    Thanks to Extreme Mechanics Letter, a new discusion of localized plastic deformation was published there. Three outlines of our work are:

      1. A new dislocation based consitutive model is built. It has a concise mathematical struture.

      2. Heat generated by plastic energy can be calculated by a mechanical version of Joule's law.

      3. Shear band and neck locations can be predicted by the mathematical model.
