Jaw Selection for Tensile Testing Grips

Tensile grip jaw selection plays an important role for successful mechanical tests as if specimen slippage between the jaws occurs or if the specimen breaks or tears in the jaw area testing may need to be discarded. This post covers the available jaw surface types for tensile grips and also the operation of quick-change type jaws.

Recovery of electrical resistance in copper films on PET subjected to a tensile strain

For flexible electronics applications it is important to understand the behavior of electrical resistance of metal films on polymer substrates under applied tensile strain. Although the growth of resistance during tensile loading was investigated in a number of research papers, the recovery of resistance during unloading remains virtually unexplored. In this paper, substantial recovery (decrease) of electrical resistance during and after unloading is demonstrated for copper films on polyethylene terephthalate (PET) substrates subjected to a tensile strain with different peak values.

Molecular Dynamics from Solid Mechanics Point of View

Choose a channel featured in the header of iMechanica: 

I am searching for a tutorial or a book which looks into molecular
dynamics method from a Solid Mechanics point of view. All I can find are
the books written for biophysicists or chemistry. I can find lot of
examples on fluids, biomolecules or polymers but none of them are on
simple solids or metals.

Can anyone suggests me a book or a tutorial which can get me ready to
write a program to simulate a simple tensile test of a metal wire (FCC
Al or some simple crystal).

Experiment 3: Mechanical Testing- Tensile Testing

The mechanical properties of a material are directly related to the response of the material when it's subjected to mechanical stresses. Since characteristic phenomena or behavior occur at discrete engineering stress and strain levels, the basic mechanical properties of a material are found by determining the stresses and corresponding strains for various critical occurrences.
