This document discusses various material properties including mechanical properties. It lists 11 categories of material properties and provides definitions and explanations for several important mechanical properties. These include fatigue strength, endurance limit, tensile strength, compressive strength, elasticity, plasticity, ductility, brittleness, malleability, toughness, stiffness, resilience, hardness, and creep. The document serves to define and explain key terms related to the mechanical properties of materials.

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
