インストロン主催の新しいインストロン・コミュニティ・ブログへようこそ。 インストロンならではの最高にフレッシュかつ頭脳明晰で才能豊かな人々の集まりです。 材料科学の世界は果てしなく広く、膨大な業界や材料、課題が対象となっています。そのため、その道の専門家、あるいは材料科学の達人になるために必要なあらゆる知識を1人で備えるのは到底無理です。 コミュニティ・ブログには、専門的ノウハウや体験、アイデアを連携して出し合い、最も正確で関連のある情報をタイミング良く読者に提供してくれる豊富な人材が集まっています。
自己紹介、意見、そして自身の体験についてお話しください。 インストロン・コミュニティでお待ちしています。
This month, Instron hydraulic wedge grips had the privilege to be on the cover of Materials Testing, a German-English materials testing journal. The journal published an article by an Instron customer about testing the fatigue behavior of construction materials.
A 57.15 mm tall and .0193 kg vertical support column withstood 4413.9 pound force at the SAMPE Seattle 2014 Conference, where Instron provided a 5969 Dual Column Testing System for the Student Additive Manufacturing Contest.
Depending on the materials you are testing and the size of your test lab, there are a multitude of ways to prepare materials testing specimens.

As one of the most trusted manufacturers of testing equipment for the plastics market, Instron has designed a tradeshow experience that takes you on a journey through the challenges (and occasional horrors) of plastics materials testing.
Gripping bent specimens is challenging, but there are a few things you do. One, flatten the tabs with a small press prior to inserting into normal grip jaws meant for flat specimens. Two, use a combination of convex and concave grip jaws to eliminate the need to flatten the specimens. Three, use a set of dual side-acting grips that will basically flatten the ends when the grips are closed.
Fatigue testing of composite materials is becoming increasingly important as they find use in a wider range of critical structural applications with the expectation of long service life. It is now widely recognized that these materials do accumulate damage over long periods of cyclic loading, even if the failure mode and mechanisms are radically different to conventional metallic fatigue.
Mechanical Project Engineer Audrey Briodeau-Line speaks with the Women's Engineering Society about working at Instron in the male-dominated engineering industry. The article tells Audrey's story of working at Instron, beginning while at an engineering university in France. In discussing her career choices, she reveals the benefits of being a female engineer, especially in a company like Instron that provides assistance for women.
