Dear Hossein Homayoun,

Let me introduce for your consideration an original method of studying the mechanical properties of polymeric materials.

Creep rate measurement with laser interferometer

Laser-interferometric creep rate meter (LICRM) is the original high-resolution method for investigation of the mechanical properties of solids, first of all, polymeric materials.

LICRM has been successfully applied to solving various problems of polymer physics and materials science. It allows to register precisely creep rates on the basis of deformation increment of 150–300 nm. This approach provided absolutely new experimental possibilities exhibiting the superiority in resolution and sensitivity to the conventional relaxation spectrometry techniques. Amongst such possibilities are creep studying on submicro-, micro- and meso-scale levels; revealing the connections between stepwise microplasticity and polymer morphology; getting kinetic information on creep at any temperature and deformation degree, the discrete analysis of dynamics within an each relaxation region; analyzing microplasticity, relaxations and phase transitions even in brittle materials; using creep rate spectra for non-destructive prediction of the temperature anomalies in mechanical behavior of materials, etc.

The report :

represents this method and some (not all) results of numerous studies performed with applying of LICRM setups for different polymeric materials in the form of bulk specimens, films or thin fibers

We are ready to provide more detailed information on your request.

Dear Sheikh Rehman

Thank you for your comment. but I want to know the new and advanced of them..

Can you say more about this or them? Which kind of mechanical testes can be determined by them?

Dear Md. Washim Akram

Thank you so much but I can't find there any new method for determining the mechanical properties of materials such as tensile or compaction tests that commonly used for mechanical properties processing. I want to know the new methods that now using instead of the common methods...

Hi,

check out this site: https://www.wki.fraunhofer.de/en/departments/hofzet/material-and-damage-analysis-computed-tomography.html

My coleagues are using Computed Tomography (CT) while performing 4-point bending tests (tensile or compression should also be possible if my memory serves well) on various composites. It's called "in situ CT" and allows neatly to determine e.g. failure mode of a material.

Dear Hossein,

a relatively recent technique compared with conventional testing machines is the dynamic-mechanical analyzer (DMA).
