Dear Colleagues,
We would like to cordially invite you to the Computational Geomechanics mini-symposium at the ASCE EMI 2020 Conference, which will take place on May 26–29, 2020 at Columbia University in NYC. The abstract submission is now open until January 15, 2020 (Link: https://submissions.emi2020.org). The mini-symposium description is given below:
Position description: Four postdoctoral research fellows and two PhD positions are now open for ERC Starting Grant wth focus on nano energy harvester. The project is financially supported by ERC Starting Grant from Horizon2020.
Hello everyone,
I have created a UMAT code for J2 elasto-plasticity with isotropic hardening for 3D solid elements.
At this point I would like to support also plane stress shell elements. What changes in the code are
suggested? The already implemented code, takes as input the strain tensor at time tn and the strain
increment tensor and updates the stress at time tn+1 and calculates the material Jacobian and
achieve quadratic convergence. The stress and strain tensors are manipulated as 6x1 vectors and the
Hi,
I have the two following INP files for Abaqus where the only difference is that in one case I'm using a CAX4R element on the other case, I'm using a CAX4RT element. Solver has been changed from one case to the other one.
This is the only difference between both cases.
Simulation time is small, so that conduction is negligible.
BUT: results in terms of Strains, Stresses and Temperatures differs.
T = 164.1°C for CX4R
T = 323.9°C for CAX4RT
The difference is Huge, what's Wrong ?

Topic
Machine learning-based approaches for modeling and numerical simulation of advanced materials.
Preferred background
Bachelor and/or Master Degrees in Mechanics and/or Material Science.
Strong multidisciplinary background with interest and experience in:
Machine learning, Artificial intelligence, Deep learning;
Material characterization, Microstructure analysis, Mechanics of materials;
Computer programming, Parallel and/or distributed computing.
To apply
Recently, there has been a growing interest in investigating the multi-functional properties of novel types of metamaterials, metastructures, and metacomposites based on triply periodic minimal surfaces (TPMS). TPMS have been discovered more than 160 years ago and thanks to additive manufacturing (3D printing) they become reality only recently and opend the doors for several applications.
How to provide a structure with a force lying on a fixed line?
We provide the answer to this question in our paper: Bigoni and Misseroni (2019) Structures loaded with a force acting along a fixed straight line, or the “Reut’s column problem”.

A PhD student is sought to perform research on systems engineering theory relying on the mathematics of probability theory, decision theory, game theory and social choice theory. The student will be supported under an NSF grant in the Mechanical Engineering department of George Mason University and work with Dr. George Hazelrigg. If interested, please contact Dr. Hazelrigg at ghazelri [at] gmu.edu (ghazelri[at]gmu[dot]edu).
