What are the three components of deformation?
The total amount of deformation between two converging bodies is described by the three components of the displacement field: translation, rotation, and strain..
What is a normal fault in science?
normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.
What is the process of deformation?
Deformation processes transform solid materials from one shape into another. The initial shape is usually simple (e.g., a billet or sheet blank) and is plastically deformed between tools, or dies, to obtain the desired final geometry and tolerances with required properties (Altan, 1983).

Is a rubber band ductile or brittle?
Rubber is not ductile. Ductility is the ability of a material to undergo permanent deformation through elongation or bending without fracturing. It’s the opposite of brittleness. It can stretch up to 500% before it breaks.
What is the difference between ductile and brittle?
Ductile: A material that can be easy bent or material can be drawn into wires. Brittle: A material that instantly snaps by external load application. Ductile: Such material will undergo plastic deformation before fracture. Brittle: These material show zero plastic deformation after stress and instantly break.
What are 2 types of deformation in Earth’s crust?
Types of Deformation Ductile deformation is irreversible, resulting in a permanent change to the shape or size of the rock that persists even when the stress stops. A fracture or rupture, also known as brittle deformation, results in the breakage of the rock. Like ductile deformation, fractures are irreversible.
What is deformation of the crust?
Crustal deformation refers to the changing earth’s surface caused by tectonic forces that are accumulated in the crust and then cause earthquakes.
What deformation leads to earthquakes?
Most natural earthquakes are caused by sudden slippage along a fault zone. The elastic rebound theory suggests that if slippage along a fault is hindered such that elastic strain energy builds up in the deforming rocks on either side of the fault, when the slippage does occur, the energy released causes an earthquake.
What is earthquake stress?
Stress is the force per unit area acting on a plane within a body. Six values are required to characterize completely the stress at a point: three normal components and three shear components. (Image courtesy of Michael Kimberly, North Carolina State Univ.)
What is ductile deformation?
Ductile deformation involves the production of large, open folds in the sediments or rocks in front of an advancing glacier, which may develop into overfolds or begin to undergo internal thrusting due to continued ice advance.
What is the difference between a joint and a fault?
Joints and faults are types of fractures. A joint is a fracture along which no movement has taken place, usually caused by tensional forces. A fault is a fracture or break in the rock along which movement has taken place.
What are the 2 types of stress that deform rock?
Stress is the force applied to a rock and may cause deformation. The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries. Where rocks deform plastically, they tend to fold.
What is the difference between elastic brittle and ductile deformation?
In elastic deformation, strain is recovered when stress is removed, but in brittle deformation, the object fractures. What is the difference between elastic and brittle deformation? In ductile deformation, the strain remains when stress is removed, but in brittle deformation, the object fractures.
What is a deformation?
1 : alteration of form or shape also : the product of such alteration. 2 : the action of deforming : the state of being deformed. 3 : change for the worse.
What type of stress causes earthquakes?
Shear stress usually happens when two plates rub against each other as they move in opposite directions. The friction of a shear stress at the edges of the plate can cause earthquakes.
What is a real life example of tensional stress?
A prime example of tensional stress is the mid-Atlantic ridge, where the plates carrying North and South America are moving west, while the plates carrying Africa and Eurasia are moving east. Tensional stress can also occur well within an existing plate, if an existing plate begins to split itself into two pieces.
What are the two major types of deformation?
When a rock is subjected to increasing stress it passes through 3 successive stages of deformation. Elastic Deformation — wherein the strain is reversible. Ductile Deformation — wherein the strain is irreversible. Fracture – irreversible strain wherein the material breaks.
What is the deformation caused by stress?
There are three types of stress: compression, tension, and shear. Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.
What are the different types of crustal deformation?
Summary. Geologic stress, applied force, comes in three types: tension, shear, and compression. Strain is produced by stress and produces three types of deformation: elastic, ductile, and brittle.
Where does brittle deformation occur?
Brittle deformation occurs commonly at the surface of the earth (lower temperature) – ductile deformation occurs at depth (higher temperatures). Folds form at depth.
