How a mass falls when attached to a flexible element with varying length?

May a catastrophe machine be realized through an elastic continuous element?
We provide a positive answer to this question in our paper: Cazzolli, Misseroni, Dal Corso. Elastica catastrophe machine: theory, design and experiments. Journal of the Mechanics and Physics of Solids.

Mechanical mismatches between implanted electronics and biological tissues can lead to inaccurate readings and long-term tissue damage. Here, we show that functionalized multi-walled carbon nanotubes twisted into helical fibre bundles that mimic the hierarchical structure of muscle can monitor multiple disease biomarkers in vivo. The flexible fibre bundles are injectable, have a low bending stiffness and display ultralow stress under compression.
Measuring forming limit diagrams (FLDs) is a time consuming and expensive process. Machine learning (ML) methods are a promising route to predict FLD of aluminium alloys. In the present work, we developed a machine learning (ML) based tool to establish the relationships between alloy composition / thermomechanical processing route to the material's FLD.
Dear iMechanicians,
Please find below a paper, co-authored with Ivan Cuesta and Norman Fleck, on the mode II fracture of elastic-plastic sandwich layers. The paper is part of the special issue in the Journal of Applied Mechanics dedicated to John Hutchinson's 80th anniversary and the Century Fracture Mechanics Summit.
"Soft magnetoactive laminates: large deformations, transverse elastic waves and band gaps tunability by a magnetic field" by N. Karami Mohammadi et al (2019) has been published in November Special Issue in Journal of Applied Mechanics.
This paper is part of my group and co-author work on the topic of Soft Magneto-Active Composites:
Abstract: Even for relatively simple thin shell morphologies, many different buckled configurations can be stable simultaneously. Which state is observed in practice is highly sensitive to both environmental perturbations and shell imperfections. The complexity and unpredictability of postbuckling responses has therefore raised great challenges to emerging technologies exploiting buckling transitions.
Dear all,
the question is in the title.
I found solutions on the web to make matlab execute an inp file making use of a user subroutine: system(['abaqus job=' Abaqusname ' user=' fortranname ' -inter']). It works well if, prior to the command, a dll file of the fortran file is created and a file 'abaqus_v6.env' is set.
However, if I want to do the same by running, from matlab, the python script which makes use of the same user subroutine, there are errors.
command in matlab: system(['abaqus cae noGUI=script.py']);
