Добро пожаловать на наш новый блог Сообщества Instron. Это подборка свежайших, ярчайших, талантливейших статей, которые может предложить Instron. Мир науки о материалах так обширен и охватывает множество отраслей, материалов и задач, и ни один человек, скорее всего, не способен обладать всеми знаниями, чтобы считаться абсолютным экспертом в области науки о материалах. Потребуется небольшая армия, чтобы совместно работая за кулисами, обмениваясь опытом, техническими подробностями и идеями, представить вам - нашим читателям - наиболее точную, необходимую, достоверную и своевременную информацию.
Мы приглашаем вас рассказать о себе, поделиться своими историями и поговорить о вашем опыте. Присоединяйтесь к Сообществу Instron.
R-value (also known as “Plastic Strain Ratio”) is a measurement of the drawability of a sheet metal. Simply put, it measures the resistance of a material to thinning or thickening when put tension or compression. R-value is a very important material property to understand for materials that will be formed into various shapes in their end use. When testing in accordance to popular standards such as ISO 10113 or ASTM E517, R-value is required.

Q: When I grip a specimen it seems that some force is already being applied. Is there a way to avoid that?

Two weeks ago we included a survey within TechNotes asking our readers to take a few moments to give us feedback on the Instron Community Blog. We received a great response and various comments on what you would like to read about. Everyone who responded will soon receive an Instron Community blog t-shirt!

One main topic in composites is “damage tolerance”. Physical testing of wind turbine blades is such an expensive proposition that virtual testing is needed as much as possible – to this end, small-scale flaw testing on a materials testing system is extremely helpful to understand and predict how the larger system will behave in service…

Implants and the materials used for their production undergo extensive tests, which include the evaluation of the static and dynamic mechanical properties of the raw materials, components, and systems. Many of these tests are internationally standardized; other testing procedures are specific to a given application. In all cases, advanced testing instruments and clamping fixtures along with flexible, programmable testing software help in the determination and analysis of the relevant data.

This month, we're featuring Randy Riddle, one of our very own Application Engineers. Not only is he a family man, a grandfather to three beautiful granddaughters, and the Mayor of Grove City, PA since 2004, but he has found the time to fit in 30 years of service at Instron.

Historically, the properties of any new material have had to be determined empirically. It can take many years to transition a material from discovery to a commercial product, which is too slow, given the range of urgent problems that advanced materials can help us solve.

Last week, we introduced a little bit of history into our blog by discussing the need to develop a testing instrument that could accurately test the new thermoplastic material of parachutes back in the 1940's .... Below, we finish the conversation by talking about the technology developed more than 50 years ago.
