Anelastic deformation. Deformation processes where a material assumes its original shape after the load is removed, but with a time delay.
Deformation is a change in the shape or size of a material due to stress or strain. It can be caused by external forces such as pressure, tension, or shearing forces acting on the material, leading to a rearrangement of its atomic structure. Deformation can result in a temporary change (elastic deformation) or a permanent change (plastic deformation) in the material.
There are generally three main types of deformation: elastic, plastic, and brittle. Elastic deformation occurs when a material returns to its original shape after the stress is removed. Plastic deformation involves a permanent change in shape due to applied stress, while brittle deformation leads to fracture without significant deformation. Each type responds differently to stress and strain depending on the material properties and environmental conditions.
In an elastic deformation, the object will return to its original shape afterwards (like tapping your arm softly with a needle, without piercing the skin). In a plastic deformation the object will first undergo elastic deformation, but then undergo a deformation that changes the shape of the material. (like tapping your arm with a needle that pierces through the skin and leaves a small wound).
The deformation would increase because the force increases.
Metamorphic rock structures are formed when rocks are subjected to high pressure and temperature, often due to tectonic forces that cause deformation. Deformation can cause rocks to recrystallize, rearrange mineral structures, and develop foliation or lineation in metamorphic rocks. Therefore, the type and intensity of deformation can significantly influence the texture and structure of metamorphic rocks.
elastic deformation
it is deformation below recrystalization temperature.
Two kinds of deformation are plastic deformation, where the material changes shape permanently due to stress, and elastic deformation, where the material returns to its original shape after stress is removed.
Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.
Elastic deformation is the temporary distortion experienced by a material under stress, where the material returns to its original shape once the stress is removed. This deformation is reversible and does not cause permanent changes to the material's structure.

Brittle objects typically do not undergo plastic deformation due to their inability to sustain significant deformation before fracturing. Instead, brittle materials tend to fracture with minimal or no plastic deformation.

The plastic deformation formula used to calculate the extent of permanent deformation in a material under stress is typically represented by the equation: ( / E), where is the strain (deformation), is the stress applied to the material, and E is the material's Young's modulus.
In compression testing, common modes of deformation include elastic deformation where the material regains its original shape after the load is removed, plastic deformation where the material undergoes permanent deformation, and fracture where the material fails. Additionally, shear deformation may occur in some materials where layers slide past each other under the compressive force.
Elastic deformation is reversible and occurs when a material is stretched but returns to its original shape once the stress is removed. Ductile deformation, on the other hand, is permanent and occurs when a material is stretched beyond its elastic limit, resulting in plastic deformation that changes the material's shape permanently.
Ductile deformation is when rock is given enough stress to break. If the stress is less, it will bend but not break.
