Rapid synchronized fabrication of vascularized thermosets and composites

Submitted by xiangzhang on

Dear colleagues,

We are happy to share a recent collaborative study on experimental and numerical investigation of  rapid synchronized fabrication of vascularized thermosets and composites. This study demonstrated that a thermoset polymer or polymer composites with embedded microvascular systems can be fabricated in a single step, using a self-propagating polymerization reaction front.  For more details, please see: https://www.nature.com/articles/s41467-021-23054-7

Nanotwin-induced strengthening in silicon: A molecular dynamics study

Submitted by mohsenzaeem on

Mechanical performance of silicon nanopillars with homogeneous and gradient nanotwinned structures are investigated through a series of molecular dynamics simulations. The most observed Σ3 twin boundary (TB) with two preferable (lowest surface energy) planes of {111} and {001} are used to generate homogeneous and gradient nanotwinned structures. Simulations of compression and tension of nanotwinned pillars reveal an extra strengthening behavior due to the addition of Σ3 TBs when compared to the single crystalline nanopillar without any TBs.

What makes plant cell walls both strong and extensible?-----a collaborative study led by Prof. Sulin Zhang and Prof. Daniel Cosgrove in Science

Submitted by yaozhangwh on

The plant cell wall possesses an unusual combination of strength and ability to expand without weakening or breaking (a quality required for plant growth), but the molecular basis for these traits has long been unclear. In a collaborative study led by Prof. Sulin Zhang and Prof.

PNAS: Compliant 3D frameworks instrumented with strain sensors for characterization of millimeter-scale engineered muscle tissues

Submitted by Hangbo Zhao on

In this work published in PNAS (https://www.pnas.org/content/118/19/e2100077118), we present compliant 3D frameworks that incorporate microscale strain sensors for high-sensitivity measurements of contractile forces of engineered optogenetic muscle tissue rings, supported by quantitative simulations.

Phase field modelling in octave

Submitted by Surendran M on
Choose a channel featured in the header of iMechanica

Hi I tried to code a basic phase field model for fracture in octave.

It doesn't seem to converge to the correct load. It fails later.

Also mesh refinement did not improve the results.

Any idea where I am wrong?

Ping me. Thanks in advance.

Mechanics to explain tsunamis---Rosakis and co-workers in PNAS

Submitted by Pradeep Sharma on

Ares Rosakis and collaborators across three other institute have just published a fascinating account of a rather unexpected mechanism for generating  tsunamis. The paper, published in PNAS, is attached with this post.

The associated press-release provides a compelling lay-person summary: https://www.caltech.edu/about/news/contrary-to-previous-belief-strike-s…
