Welcome to our new Instron Community Blog hosted by Instron. It is a compilation of the freshest, brightest, most-talented minds that Instron has to offer. The world of materials science is so vast and encompasses the broadest range of industries, materials, and challenges that no one person can possibly possess all the knowledge required to be the resident expert – or master of materials science. It takes a small army behind the scenes collaborating and sharing technical know-how, experiences, and ideas to present the most accurate, relevant, and timely information to you – our readers.

We invite you to tell us who you are, share your stories and talk about your experiences. Join the Instron Community.

### Poisson's Ratio Testing With A Biaxial Extensometer

Poisson’s Ratio has proven to be a challenging calculation for obtaining both repeatable and accurate results. To improve repeatability, we typically recommend grips that provide consistent clamping pressure, such as pneumatic side acting grips.

### Upper Yield Calculations—Discontinuous Yielding/YPE Material

Following a recent lab visit, I thought it was worth writing a quick post to share an example of how labs sometimes incorrectly calculate yield strength. While visiting a testing lab for unrelated issues, my colleagues and I were discussing how the customer runs both continuous and discontinuous material with the same method (Non-YPE and YPE). For historical reasons, they have updated their Series IX methods to Bluehill 3 with little knowledge of why, when or by whom the methods were setup.

### Industry Insights Series with David Fry

Working alongside our friends at AZOM, they developed a series of engaging interviews with a few of our global colleagues. In the recent series, I was able to discuss metals testing requirements with a focus on the latest European metals standard, ISO 6892 and high precision strain measurement with the AutoX750.

### Equipment Considerations for a Well-aligned Test

When testing stiff or brittle materials, such as composites, alignment is crucial—even instances of slight misalignment can throw off test results.

### Question from a Customer- Bagley Correction

Question: Can we compare viscosity results between polymers tested at the same temperature and identical shear rates but on two different capillary rheometers?

### Instron at Alabama Composites Conference, Birmingham

Instron was at the Alabama Composites Conference (ACC) from June 19—20 in Birmingham, Alabama. Southeast Applications Engineer Jim Gleason and Kent Wallace, Dynamic Systems, were on site. ACC is held every two years at the University of Birmingham, Alabama (UAB) and focuses on latest innovations in the composites industry. Instron is proud to support such an event because it sees participation from a wide range of industry partners working with composite materials.
