problems with piezoelectric actuator example in Matlab

While teaching piezoelectrical materials in my course at the Politecnico di BARI, I have explored the Matlab example "deflection-of-a-piezoelectric-actuator" which can be found in the official matlab web site https://it.mathworks.com/help/pde/ug/deflection-of-a-piezoelectric-actua....

The result of the example itself may be correct because it is checked against some reference solution.

Residual Stress 101: One day course at SEM conference

The day before the SEM Conference this June in Reno, Nevada, USA, we will be teaching a short course entitled Residual Stress 101: https://sem.org/annualprogram. See below for a description of the course. We will cover lots of practical material on residual stresses, much of which is not covered in standard engineering curricula. This is great material for any interested researcher who never got a comprehensive background in residual stress. It will also be great for graduate students or advanced undergrads, and students pay half price.

What causes the other: Stress cause strain or Strain cause stress ( Conjugated Polymers)

Choose a channel featured in the header of iMechanica: 

 I am struggling in understanding a theorem related to a conjugated polymer which is based on the electro-chemo-mechanical working principle.

The basic idea of the actuator is constructed from three layers, the up and bottom are conductive and the medium layer is dielectric and when the voltage applied the ions migrates to fill the holes.

It is mentioned that the expansion is happening because of the migration of the ions and then the stress occurs.

I don't agree with it as what makes the ions migrate is the electrostatic force and then the strain occurs.

How do I do multiple restarts is ABAQUS ?

Hello All,

I have been trying to restart an ABAQUS simulation using the command line. The following works fine

########

abaqus job=restart1.inp oldjob=OLD user=UMAT.f cpus=160 scratch=$PWD interactive

########

But when I do the restart for the second time like the following, It gives me an error

Real life example of Eigen values and Eigen vectors

Eigen values / vectors finds applications in most engineering disciplines and also in basic sciences. In this video, I tried to explain the  meaning of Eigen values/vectors in a simple way and gave a real life example of the same. Here is the LINK to the video.

I found a great tutorial for abaqus/cae at https://abaqus-docs.mit.edu/2017/English/SIMACAEGSARefMap/simagsa-m-Caeb... but I cannot find the main page, which I need to navigate it; I am forced to Google for individual sections guessing at what the section titles migh be; I need a URL to the root page so I can navigate the tutorial like an ebook.

Abaqus startup start-up initialization file Python script

Choose a channel featured in the header of iMechanica: 
Free Tags: 

I  need to find a startup file that Abaqus/CAE reads on startup to add a line of Python to modify the behavior the way I like it. I find myself adding this line manually every time I start Abaqus/CAE and I am tired of it. Like the .gpr file but .grp is a binary file--I cannot add things to it with a text editor. It has to be an initialization file, right? Or may be some other way to do it. Thanks in advance.

Fully Funded PhD Position on Mechanical Metamaterials at the University of Missouri, Columbia

The position: I am looking to support a PhD student to work with me towards the design, modeling, fabrication and testing of mechanical metamaterials with emphasis on morphing structures such as origami tessellations and lattice materials. The study will focus on deriving and validating novel stress-strain relationships that transcend the standard framework of Hook's law. Sought applications will be in the domains of (i) self-deploying space structures; (ii) soft robotics; and (iii) "invisibility" cloaks.

I am looking for motivated students to join my research group and work towards their PhD in the area of computational biomechanics.

Description

Almost 30% of all deaths globally are related to cardiovascular diseases, and most of these are related to changes in the stiffness of tissues making up the system. There is an urgent need for new computational tools that can help detect, understand, and treat these diseases. There are three specific projects available under his broad topic:
