Failure theories are used to predict when a material will fail due to static loading. They do this by comparing the stress ...

An international team of researchers have observed a phenomenon called virtual melting in colloidal crystals. They studied how it helps enable changes from one crystalline structure to another ...

A three-dimensional finite element model used to simulate the bolted joint is created using ABAQUS package. The stress concentration factors at the roots of the thread are first studied with a preload ...

Two types of connections were chosen: with the bolt group loaded eccentrically and subjected, essentially, to shear; and a T-stub type connection, where the bolts are subjected to tension. All models ...

Many scholars have made significant contributions to the study of the shear characteristics of rock bolts, with a focus primarily on smooth joints, while research on the roughness of joint surfaces is ...

This paper investigates the shear stress and bending moment of bolted joints made of different materials. The introduction discusses the importance of bolted joints in mechanical engineering and the ...

Stress may, then, contribute to ulcer development, but a stressed-out person may not develop an ulcer without having other risk factors, Dr. Newberry said. What Does Cause Ulcers?

But Shear did better with his next startup with Kan — a livestreaming service called Justin.tv, which started as a single channel streaming Kan's life 24/7 in 2007. In 2011, Shear spun the ...
