April 29, 2021 — Isaac Newton may have met his match. For centuries, engineers have relied on physical laws — developed by Newton and others — to understand the stresses and strains on the materials ...

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 ...

In the ongoing search for new materials for fuel cells, batteries, photovoltaics, separation membranes, and electronic devices, one newer approach involves applying and managing stresses within known ...

In this paper we consider a statistically homogeneous medium with small random variations in elastic properties. We derive the equations satisfied by the two point displacement field correlation ...

In this article, we will examine three essential aspects of flat tensile specimens: where and why they are used, how international standards and geometry influence test outcomes, and what practical ...

The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...

Multiferroic (MF) materials are materials that have both magnetic and ferroelectric properties. They are particularly interesting to materials scientists as they allow the manipulation of magnetic ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

Isaac Newton may have met his match. For centuries, engineers have relied on physical laws -- developed by Newton and others -- to understand the stresses and strains on the materials they work with.

Researchers developed a machine-learning technique that uses an image to estimate the stresses and strains acting on a material. The advance could accelerate engineers' design process by eliminating ...
