How to ask a question on iMechanica

Submitted by Biswajit Banerjee on

I've mostly had quite helpful responses from iMechanica participants whenever I've asked questions on this forum.  However, I've noticed that questions from several posters have gone unanswered.  I feel that there are two main reasons for that lack of response:

1) The questioner has not provided an adequate details by which they can be identified.  I generally don't like responding to a question posed by someone called xyz1983.

can any one suggest me a tensile testing machine for small specimens/films witha temperature ramp facility

Submitted by Bhabani K. Satapathy on

I intend to do some tensile testing on some composite materials with very small thickness (about 0.5-1mm) and size 3 cm x 1 cm in a temperature ramp mode. I would like to know the name of such a testing machine or contact if any one has the same?

Defining Tensile/Compression Strength for Plastics in ABAQUS

Submitted by braaains on
Hi.



This is a simple question about defining material properties of a plastic I guess.



I have a value for tensile & compression strength and have to include this in my model, alongside the modulus & poisson ratio. I use *Elastic for modulus & poisson, but I don't know which card to use for tensile & compression.



Have already checked the manual, but the search 'tensile compression strength' leads me to the Hashin criteria page, which is not suitable for my material.



Can anyone help?
