FEA

Do you know how to model fork support?

Do you think this is correctly modeled as fork support (picture)

minor axis bending- restrained, torsion - restrained , free to warp

 

 

Lateral torsional buckling of I beams with restraint

I am looking to model buckling of I steel beams with restraint in abaqus. But I do not know how to make rigid connections between the steel members. 

 

Why is the other beam( beam with fixed supports) not stressed? How do i define contact between the two beams.

3D FEA of stress concentration

Dear all,

 

I am simulating tensile specimens with an elliptical pore(representing a flaw in the material) in the mid-cross section of the specimen. What I am looking for is the stress concentration caused by this pore.

I am simulating this as a 3D specimen under tensile loading only, with 3D, 8-node linear brick elements(1st order). Now my questions are:

1- Is there any analytical solution for such problems(3D with elliptical pore) with which I can compare my FEA results?

how to model fastners in ABAQUS

How to model Fastners in Abaqus? I have an assembly which are connected by more than 500 fastners and has angle and channel sections? 

IS there a method to do in ABAQUS?I have assembled my model in SOLIDWORKS by providing Concetric mating for all drills, but haven't included fasteners there as that will again increase the simulation time.

PREDICTION FOR DEFORMED PART WITH TIME

Dear ALL,

Does anyone here has an experience carry out  FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.

I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.

CFP: Mini-symposium at 13th US National COngress on Computational Mechanics (USNCCM13)

We invite you to submit abstracts to this Simpleware-sponsored minisymposium

Deadline: February 15, 2015

13th US National Congress on Computational Mechanics (USCNCCM13)

July 26-July 30, Manchester Grand Hyatt, San Diego, CA

Mini-symposium - Biomechanics Modeling: Advances and Applications to Real-World Problems

Organiser: Petr Krysl, University of California, San Diego

Case Study: Modelling Ultrasonic Array Response of Real Cracks

Stress corrosion cracks can be a serious problem in many engineering industries, and especially so for critical parts. While an ultrasonic transducer can be used for the non-destructive evaluation of cracks with simple shapes, complex branching cracks, such as stress corrosion cracks, require ultrasonic arrays that consist of multiple transducers and are able to inspect at multiple angles.

Case Study: Mechanics of Bacterial Biofilms on Surgical Sutures

Biofilms represent bacterial communities that attach to implanted medical devices such as sutures and catheters. When detached from implants within the body, biofilms can cause chronic infections. This study used Simpleware software to generate image-based microscopic Finite Element (FE) models from confocal laser scanning microscopy scans of real biofilm colonies attached to a surgical suture fragment.

Simpleware Webinars: Intro to Animations Tools and New Physics Modules - February 11th and 18th

(re-arranged from January 14th and 21st)

We're running two webinars in February on the latest additions to our software ScanIP's 3D image processing, visualisation and model generation capabilities. The webinars are ideal for existing users and those wanting to learn more about creating models from 3D images.

Introduction to the new ScanIP Animations Tool on February 11th (8am/5pm GMT)

Practical Application of the Stochastic Finite Element Method

If you're interested in stochastic finite element analysis, you might like to know that we've just published a paper that reviews the "practical" application of the method. The paper first outlines the main methods of incorporating uncertainty into engineering computations. It then presents "practical" examples across a range of disciplines of where these methods have been used.

We hope that this paper is a good starting point for those looking to adopt stochastics in their work.

BOLT ANALYSIS USING ABAQUS

Dear friends,

Recently my study is focus on bolt analysis on wheel hub assembly.

In simulation using Abaqus, I try to give a certain value of tightening torque on bolt to determine the clamp force.

But, I do not know how to apply the torque value on FE model.

Can we convert torque to became as an axial force?

Or, convert torque to moment?

Simpleware Case Study: Total Hip Replacement Implant Positioning

CAD and FE models of hip implants

Positioning hip implants poses a number of challenges, particularly in terms of getting bone and implant contact right. While experimental testing can be costly, image-based modelling can be very effective at predicting the best and worst positions for implants.
