Description |
Diagrams
|
Breaking Point |
The
maximum point in which a material can elongate; the point at which
a material fails or breaks when subjected to a stress |
|
Elastic Deformation |
Temporary
deformation of a material where the material subjected to a load or
force, returns to its original dimensions once the load or force is
removed |
|
| Range
on the stress/strain curve in which a material will return to its
original state once the stress is removed |
|
|
Hook’s Law |
Law
named after Robert Hook in 1678 that describes the stress-strain relationship
in elastic materials is linear and proportional under moderate loading.
|
|
Modulus of Elasticity (Young’s Modulus) |
The
ratio of the stress inflicted on an element to the strain that is
produced |
|
Plastic Deformation |
Permanent
deformation in a material subjected to load that remains in place
after the load is removed |
|
Range
on the stress/strain curve where a material permanently deforms and
remains deformed after the stress is removed |
|
|
Stiffness |
Measure
of a material’s rigidity; a material’s ability to withstand
deformations under stress; slope of the stress/strain curve |
|
Strain |
Deformation
of the physical dimensions of an object subjected to a stress |
|
Strain Hardening |
A
stage beyond yield stress where steel goes through structural changes
that result in increased strength and resistance to further deformation
|
|
Stress |
Describes
the intensity of a force and is expressed by the amount of force acting
per unit of area |
|
Ultimate Strength |
The
maximum force that can be applied to a material without breaking the
material |
|
The point at which stress causes a material to permanently deform |
