The title of the project is as follows:
A study of the effect of imperfections on the buckling capability of a soda can under axial loading.
My group and I are aiming to carry out the following:
Linear buckling analysis of soda can to gain first 5 eigenvalues
Riks buckling analysis with...
I could not tell you whether they were cut from the same sheet or not, as the samples were already prepared for me by a PhD student who had these leftover. They were all put in the same orientation, however they did not all break near the same jaw, although most of them broke near the top one. I...
The engineering strain is equal to the change in length of a specimen divided by the original specimen length. True strain can be manipulated so that: true strain = LN (instantaneous length of sample / original length of specimen)
The engineering stress is equal to the force applied to the body...
Also, it can be seen in the image, but the grip marks on the specimen seem to be pretty linear in terms of direction, and so I can assume that the sample was properly aligned.
I am a part C Mechanical Engineering student and have been undertaking a project investigating the strain sensitivity of a particular glass filled composite.
From my quasi-static results, the stress-strain curves seem to be reasonable and match that of the mechanical material properties...
Thanks for the heads up. The pictures are attached here.https://www.physicsforums.com/attachments/upload_2015-5-2_21-31-21-png.82985/

I am a part C mechanical engineering student and require some advice for my individual project, which is based on the high strain-rate testing of a particular glass filled composite material using a split-Hopkinson pressure bar (SHPB) experiment.
I gathered the results on a SHPB test rig and...
