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.
Abstract:
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.
The link to the GIT is here

Any idea where I am wrong?
Ping me. Thanks in advance.
PhD positions in Computational Mechanics - Fracture and Contact Mechanics
We just opened at IMT School for Advanced Studies Lucca a call for PhD students for the next cycle of the PhD Programme in Systems Science, Track Computer Science and Systems Engineering.
People interested in computational mechanics and tribology should mention MUSAM -Multi-scale Analysis of Materials- in their motivation letter and in the online form.

Tensile tests are used to determine how materials behave under tension load. In a simple tensile test, a sample is typically pulled to its breaking point to determine the ultimate tensile strength of the material. The amount of force (F) applied to the sample and the elongation (∆L) of the sample are measured throughout the test.
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…
There is a Ph.D. position ( guaranteed paid research assistant for two years ) in the Energy, control, and Optimization (ECO) lab for Fall 2021 in the Mechanical Engineering department at Stevens Institute of Technology.
The project is related to the fundamental study of radiation heat transfer in thin-film nanomaterials. Prior computational knowledge and experience with heat transfer in nanomaterials are required. Being familiar with FDTD, COMSOL, MATLAB, and Optimization algorithms is a Plus.

This blog post covers the description and determination of Young’s modulus, tangent modulus, and chord modulus. These properties, commonly used for product and material specification, can be calculated by subjecting a specimen to uniaxial force, measuring its stress and strain properties, and generating a stress-strain curve. The accuracy of the modulus determination depends on the precision of the load and strain measurements.
