How does deformation occur?
When a sufficient load is applied to a metal or other structural material, it will cause the material to change shape.
This change in shape is called deformation.
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..
What are the 2 types of deformation?
Deformation can be of two types as follows:Permanent Deformation – Also known as plastic deformation, it is irreversible. It is a type of deformation that stays even after the removal of applied forces.Temporary Deformation – Also known as elastic deformation, it is reversible.
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 is the meaning for antonym?
: a word of opposite meaning The usual antonym of good is bad.
What is the opposite of deformed?

Is milling a deformation process?
Machining, milling, and boring are all subtractive processes that create or modify shapes. The focus of this chapter is on the second category, solid deformation processes in which a dense, solid starting material is converted into a shape by the application of mechanical forces.
What is the difference between bulk deformation and sheet metalworking?
The key difference between bulk deformation and sheet metal forming is that in bulk deformation, the work parts have a low area to volume ratio whereas, in sheet metal forming, the area to volume ratio is high. Deformation processes are important in transforming one shape of a solid material into another shape.
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 are the four basic forms of deformation of solid bodies?
3 Introduction Forces result in four basic forms of deformations or displacements of structures or solid bodies and these are: TENSION COMPRESSION BENDING TWISTING Torsion is one of the common modes of deformations in which shafts are subjected to torques about its longitudinal axis resulting in twisting deformations.
What are the 3 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.
How does plastic deformation occur?
Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
How is deformation calculated?
Strain is a measure of deformation representing the displacement between particles in the body relative to a reference length. A general deformation of a body can be expressed in the form x = F(X) where X is the reference position of material points in the body. … A deformation has units of length.
What is a plasticity?
Plasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture (see yield point).

What is creep failure?
Creep may be defined as a time-dependent deformation at elevated temperature and constant stress. It follows, then, that a failure from such a condition is referred to as a creep failure or, occasionally, a stress rupture. The temperature at which creep begins depends on the alloy composition.
What is tensional stress?
Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.
What are the forming process?
Deformation processes can be conveniently classified into bulk-forming processes (e.g., rolling, extrusion, and forging) and sheet-forming processes (e.g., stretching, flanging, drawing, and contouring).
What types of deformation may occur in forming processes?
A forming operation is one in which the shape of a metal sample is altered by plastic deformation. Forming processes include stamping, rolling, extrusion and forging, where deformation is induced by external compressive forces or stresses exceeding the yield stress of the material.
