Cutting process simulation in Abaqus

Hello ,

 I am working on a project using abaqus to
simulate miling process. As the first stage, I have to be able to simulate cutting process in Abaqus. I have looked up Abacus 6.11 documentaion a lot but did not find too much of usefull information. Could any one kindly give some hints how to develop such model or introduce me some usefull complete resources?

Regards,

Reza

Two postdoctoral positions available at NIST

The Biosystems and Biomaterials Group at NIST has two postdoctoral positions available for recent PhD graduate to work on (1) simulation of photon transport (light migration) in polymeric composites (2) modeling of cell-material adhesive interactions. These interdisciplinary research programs require the prospective applicants to have a strong background in computational methods (finite element or MD).

Simulation of fracture toughness test

Choose a channel featured in the header of iMechanica: 

Hi, I am new to ABAQUS. I want to simulate the fracture toughness test to predict the behaviour of materials(brittle/ductile). Please help me how can I proceed?

If possible give me some guidelines and if you have any documents regarding this topic kindly send it to: sufian.ulsan@gmail.com

Thanks in advance for your valuable suggession.

Simulation of Hail Impact Using the Smoothed Particle Hydrodynamic Method in Abaqus/Explicit

Ice or hail impact is an important design consideration in the aviation, energy, and astronautics industries.  Physical testing of impact scenarios can be expensive and impractical.  Numerical simulations provide cost effective and convenient tools for including hail impact scenarios in the design process.

Abaqus multiscale bridge with UMAT

Choose a channel featured in the header of iMechanica: 

Hello,

I'm trying create a bridge between scales using Abaqus, UMAT subroutine.

On macro scale I call UMAT, which calls other abaqus inp. with this example code

call SYSTEM('abaqus cae script=C:\Temp\mixUMAT\simpleModel.py -- A 2 5.3')

And my "simpleModel" receives all arguments properly.

However, I need some values which are calculcated on "simpleModel", to UMAT continues the executation.

Anyone knows  how can I do it?

 

Thank you!

2D modelling of laser welding

while carrying out a simple 2D analysis of welding of butt joint considering the source of constant heat flux and applying it at certain nodes as constant heat flux, i encountered a problem that it says that the temperature at particular node is exceeding the pre set limit and no solution is obtained. I am a freshman in Ansys so any help in this regard will be helpful

Designing Safer Vehicles with Realistic Simulation of Airbag Deployment

Airbags are one of the major protection systems used in a car crash. They play one of the most important roles in preventing severe injuries and fatalities during vehicle crashes. The advancement of new technology and airbag regulations necessitates that airbags be tested for safety in all kinds of scenarios, including situations where the occupant interacts with the airbag before it is fully deployed.
