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.

Rgds.

STRESS TRIAXIALITY

Dear ALL,

Which reading material/source that describes the good understanding of stress triaxiality?

What is the role of stress triaxiality for FE analyst?

I have read a lot of papers/articles but still have confusing me on the fundamental of stress triaxiality.

 

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?

Postbuckling and Progressive Damage Analysis

Salam and Hi!

Can anyone share here, your understanding on POST BUCKLING and PROGRESSIVE DAMAGE ANALYSIS.

My 1st Paper!

Salam and Hi!

My 1st paper was published in Jurnal Mekanikal UTM in June 2008. Please comment and critic on my research works! The paper is here, PREDICTION OF PROGRESSIVE FAILURE IN WOVEN GLASS/EPOXY COMPOSITE LAMINATED PANELS

Thanks!

Strain Gage Measurement

Salam and Hi!

Can anyone share how to determine/convert from Volt Data to Strain Data (volt to strain in mm) after I did experimental works by using strain gage. What is the formula?

Visual Fotran 7.61

Hi

Anyone here who has an experience run a subroutine by using Visual Fotran 7.61. Can we run subroutine from VF 7.61 with ABAQUS 6.5? Is it compatible both together?

Please help me!

Thanks.
