In addition, the agreement between theory and experiment for a variety of materials suggests that ... Nemat-Nasser, S. Brittle failure in compression: Splitting, faulting, and brittle-ductile ...

Failure theories are used to predict when a material will fail due to static loading. They do this by comparing the stress state at a point with material properties that can be easily determined from ...

Catastrophic breakage of brittle materials such as ceramics ... Pons and Karma's idea could be taken is the study of failure in biological materials — for example, spider silk, nacre and bone.

Many of the atomic mechanisms of materials failure however still remain a mystery ... California study the dynamics of brittle crack propagation with large-scale atomic simulations.

A material that previously had some flexibility, for instance, may become brittle. "As we design materials ... higher temperatures for longer before failure. The team also sees the potential ...

Brittle materials generally have lower impact stregths ... starting with small strikers and working up until failure occurs. Izod Tests at Different Temperatures Tests are often performed at different ...

Most existing research efforts on stretchable electronics focus on the organic-based stretchable electronics because it is generally conceived that the widely used silicon is brittle and cannot ...

(PhysOrg.com) -- The weak tendons and fragile bones characteristic of osteogenesis imperfecta, or brittle bone disease ... analysis of the role of a materials' failure in human disease, a paper ...

but also very brittle (as in, not tough). Small shears can spread as cracks, resulting in material failure. However, the crystalline structure of metals can provide microstructual obstacles that ...

One theory that is used for the prediction of failure in a ductile material is the maximum shear stress theory (MSS). The basis of this theory is that failure will occur when the maximum shear stress ...

Metals will weaken, or soften, and polymers may stiffen as the strain approaches the state of materials failure. "It is only for infinitesimal ... for understanding and predicting the dynamics of ...
