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.

As we enter spring, spiders are becoming a nuisance as they make their silky homes on our patios and porches. However, not all byproducts of spiders are considered a nuisance. Not only does Spider-Man boast the super strength of spider silk, but the textile Kevlar® was developed with properties that compare to the fiber. Now, scientists have uncovered fascinating new facts about this material that offer intriguing possibilities for the future. Learn more about these discoveries and the growing repertoire of spider silk uses

Q: What is the most effective gripping technique for a composite specimen with a hard, smooth surface?
Posted On Apr 19, 2012
Bamboo is a natural composite material comprising cellulose fibers embedded in a lignin matrix. The cellulose fibers are aligned along the length of the bamboo providing maximum tensile strength and rigidity in that direction. Moreover, the fibers are most abundant on the outermost part of the bamboo stem while the inner part of the stem is hollow, meaning that bamboo is strong, stiff, and light.

When testing composite specimens, effective strain measurement often requires the direct bonding of strain gauges to the specimen. It is generally not possible to connect individual strain gauges directly to materials testing systems since the electronics are typically designed for a "full Wheatstone bridge" whereas a single strain gauge is only a "quarter bridge".

With NPE well underway in sunny Orlando, FL, we've heard from our colleagues in the booth about the excitement and energy that's filling the 920,000 square feet of exhibiting space. Also, one note of surprise is that a lot of the attendees who stop by the booth are not aware that CEAST products are a valuable part of the Instron line.

According to the Center for Disease Control and Prevention, motor vehicle crashes are the leading cause of death in the US among people ages 5-34. About 6,400 adults are injured in motor vehicle accidents every day. Still, nearly 15% of us don’t buckle up for every trip we take in our cars.

Stents are a wonderful creation of modern medical engineering that aid physicians and surgeons in the treatment of heart disease. Conditions, such as smoking, diabetes, and high cholesterol help promote atherosclerosis, the build up of fatty plaque within arteries, which can ultimately lead to heart attack and stroke.

Have you heard of 21 CFR Part 11? If not, it is a set of compliance requirements that allow for safe and secure storage and submission of electronic records for industries regulated by the US FDA. In other words, this is the FDAs procedure for quality control of electronic data. Any company storing electronic data that could be audited by the FDA must comply with this set of requirements. Although the FDA still permits paper-based data storage and submission, this approach can lead to higher costs, increased time to market, decreased quality, and challenges with information storage availability, retrieval and portability, as compared with electronic methods.
