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 ...
Many complex fluids, such as surfactant mesophases, network forming polymers, emulsions etc. do not flow until the applied stress crosses a certain critical value, called the yield stress. Materials ...
The stress value then levels off at the equilibrium value (Figure 7). Figure 7. Illustration showing the stress evolution of a yield stress material at constant shear rate. Normally, a low value of ...
Researchers show how blister shapes in atomically thin materials like graphene can be used to map pressure, membrane tension, and surface adhesion. (Nanowerk Spotlight) Anyone who has ever struggled ...
The fields of finite-element analysis, failure analysis, and solid mechanics all express stresses in terms of tensors. Engineering literature usually treats a tensor as a symbol dressed with indices ...
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.
