CutExtrude error Abaqus

Submitted by dotsrcool on
Choose a channel featured in the header of iMechanica

Hi all, 

I'm trying to create a full-scale truss for a static loading simulation using Abaqus.
I wanted to use a Python script to do this, but I am not very experienced with this language or the Abaqus methods.

The members forming the truss are cee sections. However, at the ends of the cee sections I want to create an extruded cut

like so:

However, when I try to use the CutExtrude command, Abaqus keeps giving me an "Invalid sketch plane" error even though I'm sure that the face I'm putting in the CutExtrude method is correct.

Hello everyone , 

LAMMPS suggests a script to calculate C44 , C11 & C12 .The question is : How to calculate the others for a nanomaterial ? Thanks in advance !

Post-doctoral position in Montréal on crystal plasticity in collaboration with the aerospace industry

Submitted by martin.levesque on

Hi

I am looking for a 12-15 months post-doctoral fellow to work on crystal plasticity finite element simulation of impacts. This project is parts of a larger collaborative project with Pratt and Whitney, Bell Helicopter, L3 and Héroux Devtek aiming at understanding the effects of shot peening on fatigue life. The project involves 3 other post-doctoral fellows and 4 PhD students.

The starting date is flexible and could be as soon as now, depending on the candidates expertise.

The interested candidates are invited to send me their CV and publication lists.

sound propagation simulation in abaqus challenge

Submitted by shabuK on

Dear friends,

           I am simulating sound propagation in mild steel.

frequency=5MHz mesh size=0.5mm

time incriment of wave amplitude=1e-9

instead of giving force at a node i have given boundry displacement

U1=5.8e-10

U2=-8e-10

instead of showing sound propagation, my entire specimen(mild steel with 15 mm thickness) deflecting like a wave.I would like to know 1)what is the reason for that deflection?

2)what may be the possible solution?

Asymmetric flexural behavior from bamboo’s functionally graded hierarchical structure: Underlying mechanisms

Submitted by Yang Lu on

As one of the most renewable resources on Earth, bamboo has recently attracted increasing interest for its promising applications in sustainable structural purposes. Its superior mechanical properties arising from the unique functionally-graded (FG) hierarchical structure also make bamboo an excellent candidate for bio-mimicking purposes in advanced material design. However, despite its well-documented, impressive mechanical characteristics, the intriguing asymmetry in flexural behavior of bamboo, alongside its underlying mechanisms, has not yet been fully understood.

Development of a Biofidelic Human Head Model from MRI data

Submitted by Simpleware on

 

Traumatic brain injuries from head impact are a major issue across areas such as defence, automotive and sports, and can be costly to research using experimental testing. These injuries can be explored, though, through 3D models created from scan data and computer simulations.
