Which stress is considered for the failure of ductile materials: ultimate or yield stress?Yield Stress:Yield stress is the amount of stress that is needed to change the deformation of material from elastic to plastic. Elastic deformation is the region where the material has...
Materials Design Processes Units Formulas MathMaximum Shear Stress Criterion The maximum shear stress criterion, also known as Tresca's or Guest's criterion, is often used to predict the yielding of ductile materials. Yield in ductile materials is usually caused by the slippage of crystal planes ...
Ductile materials exhibit massive amounts of plastic buckling or deformation in comparison to brittle materials. In a ductile fracture, the crack grows at a slow pace and is accompanied bya great deal of plastic deformation. In this case, the crack does not expand except when high levels of ...
George, in Encyclopedia of Materials: Science and Technology, 2001 1.5 The Effect of Temperature on Ductility NiAl alloys show quite marked brittle-to-ductile transitions at 500–600K, whose temperatures depend on strain rate, composition, grain size, and orientation for single crystals (see Fig....
undergoes long-term exposure to harsh thermal and mechanical conditions, a feature where conventional soft magnetic materials fail to function. Future efforts on designing strong and ductile soft magnetic MCAs for high-temperature applications could target higher saturation induction and lower coercivity ...
Our analyses confirm the existence of two distinct void growth mechanisms, i.e., void-by-void growth mechanism for materials containing small initial void volume fractions and multiple void interaction mechanism for materials containing large initial void volume fractions. As an example, Fig. 4 shows...

These are the extension of...
