brittle. ceramics are generally brittle.
Ductile materials are those that can undergo a large plastic deformation without brittle failure or fracture occurring. In other words ductile material can be stretched without breaking. For example a ductile material can be stretched into a wire.Ductility is a solid material's ability to deform under tensile stress.1. Easily drawn into wire or hammered thin: ductile metals.2. Easily molded or shaped (malleable)3. Capable of being readily persuaded or influenced (tractable)
renal failure
The ability to learn from that failure. As Thomas Edison said, "I have not failed. I've just found 10,000 ways that won't work."
swimming failure
Lung failure and death.
It will break or fail. The type of failure will depend on how brittle/ductile it is. Brittle material will break cleanly, while ductile material will deform to varying degrees.
For materials that are brittle rather than ductile. For ductile :max shear stress theory would be more suitable
For ductile materials, teh VonMises theory is used; it combines tension and shear stresses in a different way than principal stress, which is used for brittle materials. In either case, its value is compared to the normal (tension/compression) stress allowable for the particular material.

Ceramics, glasses, minerals and aggregates of cemented of minerals (i.e. rocks) are all examples of brittle solids. There are probably many others you can think of!
There are two reasons. First, faulting is a form of brittle failure, which generally occurs at lower temperatures. Deep in the crust, where it is very hot, rocks tend to undergo ductile failure, deforming like taffy. Additionally, most materials resist breaking at higher overall pressure.
semiconductors
Yes, it is - it has a yield point and can strain quite a bit 20% or so before failure
This depends on the confining pressure, the temperature and the strain rate applied to the mineral. In general for minerals (and other materials), the lower the rate of strain, the more likely ductile or plastic creep deformation will occur. The higher the strain rate, the more likely brittle deformation is to occur. As the confining pressure increases, an objects shear strength will increase (this usually coincides with a greater depth of burial) and due to the earth's thermal gradient an increase in temperature. As the shear strength increases, brittle failure is less likely and the higher temperature means that plastic deformations or creep are more likely to occur.
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
He didn't. He dropped out of hghschool. Never looked back at it as a failure. He's right.
