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 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 ...

Durability of components under dynamic load can be increased by understanding the origin of the stress and strain distribution. While numerical simulations based on finite element (FE) models can help ...

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 ...

A proposed calculation of in situ closure stress allows engineers to select more appropriate proppant. For decades, the calculation for in situ closure stress on proppant has involved subtracting ...

Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...
