Abstract

The effect of local inertia around the crack-tip in dynamic fracture of soft materials

Phase-field or gradient-damage approaches offer elegant ways to model cracks. Material stiffness decreases in the cracked region with the evolution of the phase-field or damage variable. This variable and, consequently, the decreased stiffness are spatially diffused, which essentially means the loss of the internal links and the bearing capacity of the material in a finite region. Considering the loss of material stiffness without the loss of inertial mass seems to be an incomplete idea when dynamic fracture is considered.

Fully funded PhD Positions within new HetSys Centre for Doctoral Training at Warwick for October 2019 start

HetSys is an entirely new EPSRC-supported CDT which will train people to challenge current state-of-the-art in computational modelling of heterogeneous, real-world systems across a range of research themes such as nanoscale devices, new catalysts, superalloys, smart fluids, laser-plasma interactions etc.

Multiple Ph.D. Positions focusing on real-time SHM, structural mechanics, and intelligent infrastructure at the University of South Carolina

Dr. Austin Downey in the Department of Mechanical Engineering at the University of South Carolina is looking for multiple Ph.D. students who wish to work in the fields of real-time structural health monitoring (SHM), structural mechanics, structural control, and intelligent infrastructure. Successful candidates must be excited to work in an interdisciplinary and international environment that will fuse concepts from solid mechanics, machine learning, real-time computing, prognostics, and multifunctional materials.

Post-Doc position for “Computational Soft Contact Mechanics”

The Center for Biomolecular Nanotechnologies in Lecce is currently seeking a highly motivated and talented candidate with background in computational contact mechanics, fluid dynamics, modelling and simulation of interface mechanics, or related areas.

The objective of the project is to develop numerical models for the simulation of the interface processes occurring during the wetting/dewetting of thin fluid films among and across soft interacting interfaces, in order to predict the local interface flow and dissipation dynamics.

How to automate surface creation in Abaqus ?

Free Tags: 

I would like to create a surface (on top side of a cube) in Abaqus

I am aware of doing it manually by using the following in GUI :

 

1) Tools->Surface-> Create

2) Select regions for surface by the angle

 

This is what I tried and failed :

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.
