Runing of input file

Dear friends,

if i have one input file i will import by file---model---inputfile

the i will see what they did in othermodules, for learning from exapmle problem

but if i have morethan one input file mean main input file and node information and element information both are seaprate input for reduc thesize of file.

how to import via part--model--

so how to merge this more than one input file 

thanks and regards

Neuber Plasticity correction


Can we used Neuber Plasticity correction method to composite material to estimate equivalent elasto-plastic stress from linear elastic stress results ?

Can anybody provide some document which support the usability of Neuber method to composite ?

Notes On Linear Static Analysis & Dynamic Analysis

Hi friends i am new user and 1 year experienced guy in CAE field in  Pune, India.

    i wants some tips/notes in Linear Static Analysis & non Linear analysis.

 Tips/ Notes about softwares like MSc nastran, Abaqus will be useful for me. So plz tell me how can i obtain them.

elastomer gasket life prediction

my project is life prediction of elastomer gaskets in ic engines using fea.     how can i select the constitutive model and the life prediction associated with which mechanism whther stress relaxation, stress softening or  excessive creep

Thank's all in advance.

How to import Ls-Dyna files(*.k) to Abaqus CAE 6.7 Edu version

How to import what i beleive is Ls-Dyna files with an extension (.k) in to Abaqus CAE 6,7 edu version?? . Any free translaters are available or can it be done with Abaqus itself ??

 Thx in advance

Concreate Prestress Model Not converge in step Loading

Dear Sir,


             I 've mater thesis project about prestress concreate bridge. On the first step I used Bolt load for represent prestress on Tendon

to hold all bridge block. And second step I apply load on vertical load such as 3 point bending test. On the first step I can run it completed. But on the second step it not converge. I need some comment for help mesolve this problem


                                                                                                                        Thanks you

Deformation 'Gradient', Right/Left Cauchy Green Compatibility

I post some (hand-written) notes on compatibility conditions for both small and finite strains that I have used for helping me in lecturing. These may be useful for our student friends on imechanica. I also post a paper on compatibility conditions for the Left Cauchy-Green field in three dimensions as well as the paper by Janet Blume on the same subject.

crash/error message

Could anyone let me know the reason why Abaqus/CAE closes with the crash/error message when you submit or want to visualise your result.

How to find max stress in the short beam

Choose a channel featured in the header of iMechanica: 

Hi Every one,

It is immense pleasure to meet all you in this technical forum.

I have a basic query in strength of materials

This is about of short beam

Beam dimensions are
L=7.375 mm
Dia =15.05 mm
Tip Force=27514 N

For the above beam, following are the geometrical properties

area=177.894 mm^2
IZZ=2518 mm^4

For this kind of beam, how should we approach so as to determine the maximum stress in the component.

Information on cad/cam/pro - e courses

Dear Sir/ Mam,

I am a Diploma holder in Mech. Engg. with 10 years experience in QC and 4 years experience in drafting.

          I have already completed a course in AutoCad 2000 in 2D and 3D. I am interested in persuing course in CAD/ CAM/Pro - e. Please guide . Please give details of institutes in Kolkata offering the said courses. Thank you

Dr. Ranjan

May I get the technical difference ansys is having over abaqus or Nastran. Or may I ger the URL where I can get the information.

FEM error message


I have been struggling with the following error message in FEMLAB software: "The length of fem.appl(1).equ.ind must equal the number of domains in the geometry." I don't know exactly how to fix this error message. Would you please help me?

 Thank you, Yoon
