  • Brittle Material - an overview ScienceDirect Topics

    Brittle materials include , ceramic, graphite, and some alloys with extremely low plasticity, in which cracks can initiate without plastic deformation and can soon evolve into brittle breakage. Apparently, the microcutting model is not suitable for such materials. It has been experimentally shown that as a single particle impacts the brittle material, cracks generally occur at those ...

    2020-6-2  Since brittle materials are capable of absorbing a very limited amount of energy, they are not usually desirable when constructing or building durable objects, such as foundations or bridges. In fact, in these cases, brittleness is usually imposed by other materials, which in turn have indispensable specific properties, such as resistance to rust .

  • Brittle Materials - spiedigitallibrary.org

    A material is considered to be brittle if it exhibits low strain at failure when subjected to stress. In other words, unlike ductile materials, it has very little plastic capability and hence no specific yield point. Many optics—both refractive lenses and reflective mirrors—consist of brittle materials.
