Dear Editors,

The first step of starting EML looks promising and with the help of academic people in this community, I think EML has generated enough heat with lots of interesting view points.

We all know that there has been lots of discussion in the imechanica community regarding open source journals, had any one thought about making EML fully open source?.

Thanks and Regards,

Dear All,

             There is an excellent tool called Mendeley that can be freely downloaded from (www.mendeley.com). It helps you in organizing the literature collection and  in optimizing the literature review process.

Thanks and Regards,

Hi ,

Due to  Thermal ratcheting in cylindrical pipes carrying hot fluids that are used in nuclear applications, the pipe bulges. I am about to start a project to study why this bulge comes and how to rectify it. It would be very helpful to me if  some of you can give your valuable suggestions and references in the area of Thermal Ratcheting in pipes.

Thanks and Regards,

Hi all,

 I am working on simulation of necking in a uniaxial tension test using sheet specimens of 1 mm sheet thickness. I have given stress strain data upto a plastic strain of 1 , I am using 4 elements in the thickness direction of the sheet.My job is able to complete but with lot of warning messages as follows:

1) The strain increment has exceeded fifty times the strain to cause first yield at 286 points

2) The system matrix has 174 negative eigenvalues.

Hi,

     The data obtained from tensile test is not reliable after the point of maximum load as neck initiates and triaxial state of stress develops.There is lot of literature in this regard, Can anyone suggest a good method to obtain the exact load disp curve after necking.

 regards
