4. Fatigue strength
 Fatigue strength is the highest stress that a material can
withstand for a given number of cycles without breaking

5. Endurance limit
 In fatigue testing, the maximum stress which can be appl
ied to a material for an infinite number of stress cycles wi
thout resulting in failure of the material.

6. STRENGTH
 The ability of a material to stand up to forces being applied without it
1. Bending
2. Breaking
3. shattering or deforming in any way.

7. Compressive strength
 Compressive strength is the capacity of a material or
structure to withstand loads tending to reduce size.

8. TENSILE STRENGTH
 The ability of a material to stretch without breaking or
snapping.
 The tensile strength of a material is the maximum amount of tensile
stress that it can take before failure, for example breaking.
 There are three typical definitions of tensile strength:
 Yield strength - The stress a material can withstand without
permanent deformation. This is not a sharply defined point. Yield
strength is the stress which will cause a permanent deformation of
0.2% of the original dimension.
 Ultimate strength - The maximum stress a material can withstand.
 Breaking strength - The stress coordinate on the stress-strain curve at
the point of rupture.

10. ELASTICITY
 The ability of a material to absorb force and flex in
different directions, returning to its original position.

11. Plasticity
 plasticity describes the deformation of a material
undergoing non-reversible changes of shape in response
to applied forces

12. DUCTILITY
 The ability of a material to change shape (deform)
usually by stretching along its length.
 Ductility may be expressed as either percent elongation
(% plastic strain at fracture) or percent reduction in area.

13. Brittleness
 A material is brittle if, when subjected to stress, it
breaks without significant deformation (strain). Brittle
materials absorb relatively little energy prior to fracture,
even those of high strength

14. Malleability
 Malleability is a substance's ability to deform under
pressure (compressive stress). If malleable, a material
may be flattened by hammering or rolling.

15. Toughness
 Toughness is the ability of a material to absorb energy
and plastically deform without fracturing

17. Stiffness
 Stiffness is the rigidity of an object — the extent to
which it resists deformation in response to an
applied force

18. Resilience.
 resilience is defined as the maximum energy that can
be absorbed within the elastic limit, without creating a
permanent distortion.
 The modulus of resilience is defined as the maximum
energy that can be absorbed per unit volume without
creating a permanent distortion

20. Hardness
 Hardness is the resistance to plastic deformation (e.g., a
local dent or scratch). Thus, it is a measure
of plastic deformation, as is the tensile strength, so they
are well correlated. Historically, it was measured on an
empirically scale, determined by the ability of a material
to scratch another, diamond being the hardest and talc
the softer.
 There are a few different hardness tests: Rockwell,
Brinell, Vickers, etc. They are popular because they are
easy and non-destructive (except for the small dent).

22. Creep
 The progressive deformation Of machine component
under the load at high temperature is called creep
