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 ...

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 ...

If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Did you know that the typical stress-strain curve obtained from a uniaxial tensile test is just an approximation? It doesn't consider the fact that the dimensions of the test specimen change ...

This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object responds to externally applied loads. Stress is a measure of the distribution ...

New research shows that the electronic structure of metals can strongly affect their mechanical properties. New research from the University of Birmingham shows that the electronic structure of metals ...

• Structural properties of bolted joints depend on bolt and clamped-member stiffnesses. • Clamped members can be treated as a sleeve or hollow cylinder. Sound designs of bolted joints rely on a good ...
