RAILWAY AGE, MARCH 2023 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that professionals in the railway industry have asked to learn more ...

Some natural organisms, such as bone and coral reefs, have an incredible ability to adjust to varying amounts of stress, drawing on nearby minerals for structural reinforcements as the need arises.

Cut open a bone and you'll see a subtly disordered structure. Tiny beams, called trabeculae, connect to one another in irregular patterns, distributing stress and lending bones an impressive toughness ...

Scientists were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight. Working on the ...

Jointing is a basic function of engineering. For example, bolting two parts together can involve material properties and loading forces. Here, we will focus on preloading, shear and tear-out in a ...

Knots are known for boosting the strength of materials, from the tiniest twists of DNA to (potentially) the very fabric of the universe. Now, Caltech engineers have developed a new material consisting ...

A new material may be the key to quickly flag damaged infrastructure. This material offers a way to reduce the manpower required to regularly monitor structures that undergo daily use such as bridges.
