Brittle deformation is favored over plastic deformation in situations where the material is under low temperature, high strain rate, low confining pressure, or lacks ductility. Additionally, brittle deformation occurs in materials with strong atomic bonds that tend to fracture rather than deform permanently.

What would happen if the force causing the deformation became greater?
The deformation would increase because the force increases.
What is a noun for brittle?
Brittle is an adjective. The noun form would be brittleness.
What do you mean by brittleness?
Aptness to break; fragility.
Would iron shatter if dropped?
No, iron is a strong and durable metal that is not brittle like glass, so it is unlikely to shatter if dropped on a typical surface. However, repeated drops or a drop from a significant height could still cause deformation or damage to the iron object.
Would quartzite or sandstone break more easy?
Quartzite is generally harder and more resistant to breakage compared to sandstone. Quartzite is a metamorphic rock that has undergone high heat and pressure, making it more durable and less prone to fracturing. Sandstone, on the other hand, is a sedimentary rock that is softer and more easily eroded, making it more likely to break.
Why would metals behave as brittle materials without dislocations?
Metals behave as brittle materials when lacking dislocations because dislocations help accommodate plastic deformation by allowing atoms to rearrange and slide past each other. Without dislocations, stress builds up and results in sudden fracture when the yield strength is surpassed, leading to brittle behavior.
What is the difference between brittle and ductile with two examples of each?
Brittle materials fracture without significant deformation when subjected to stress, while ductile materials can deform significantly before fracturing. Examples of brittle materials include glass and ceramics, which break easily. Examples of ductile materials include metals like copper and aluminum, which can be bent or stretched without breaking easily.
Why plastic deformation important in metal not in ceramics?
Plastic deformation in metal causes it to change shape, usually under stress such as a spinning turbine vane. Ceramics cannot deform, they are too hard and would shatter.
Would a salt react with plastic?
salt will react with rubber in the presence of heat, rubber can get brittle.
What is it called when a force causes an object to change its shape?
When a force causes an object to change its shape, it is known as deformation. This can occur either temporarily (elastic deformation) or permanently (plastic deformation) depending on the material properties and the applied force.
Difference between elastic and plastic deformation?
Elastic deformation returns to it's original shape after a strain is applied. Plastic deformation returns to a deformed shape after a strain is applied. The material's molecular bonds are strained to the point of fracture, making it not possible to return to the same state. Elastic deformation will return to its original shape. Plastic deformation is when you alter the original form. To understand more on this subject you might investigate failure analysis literature. Lots of good stuff there ratchet marks, beach marks, reverse bending etc... I believe the U.S. metallurgical society has the best reference material on this subject. A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape, is called elastic deformation. In other words, elastic deformation is a change in shape of a material at low stress that is recoverable after the stress is removed. Examples would be the loading of a bridge or building support beam where the loads remain within the original design parameters, or the use of a safety pin where when it is opened it returns to it's unloaded shape. When the stress is sufficient to permanently deform the metal, it is called plastic deformation. Examples would be the building support beams for the twin towers, where the heat generated by the fires decreased the strength of the steel and allowed it to deform plastically, or the loads that are applied to a section of electrical conduit or mechanical piping in order to bend them into a specific shape. in elastic def. , the material returns to its original shape once force is removed. in plastic, the deformation is permanent and the material doesn't return to its original shape the elastic deformation happens in yield point and elastic deformation back to original size but plastic deformation will not back tto original size.
Would glass or plastic shelving be better in a freezer and can you explain your choice?
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
What would happen if the force causing the deformation became greater?
The deformation would increase because the force increases.
What is a noun for brittle?
Brittle is an adjective. The noun form would be brittleness.
How would you explain a horizontal sedimentary rock layer containing Cambrian fossils lying on top of a rock layer containing Ordovician fossils?
The Adirondack rocks have been both severely folded and sheared by ductile deformation and shattered by brittle.
What would be the opposite of brittle?
The opposite of brittle would be flexible or resilient.
How would you use the word 'brittle' in a sentence?
Window glass is brittle.
