1
Q

Hardness test

A

A materials resistance to permanent deformation, indentation or scratching.

2
Q

Flexure

A

The application of a force that causes the bending of an object.

3
Q

Compression

A

The force of a load applied axially on an object in a squeezing manner.

4
Q

Shear

A

Is the application of 2 equal and parallel forces on an object from opposite directions.

5
Q

Tension

A

The force of a load applied axially on an object in a stretching manner.

6
Q

Torsion

A

The application of twisting force on an object.

7
Q

Fracture toughness

A

The resistance of metals to brittle fracture propagation in the presence of stress raisers.

8
Q

Fatigue

A

The failure of a material under cyclic stresses that have a max. Value less than the static tensile strength of the material.

9
Q

Dynamic capacity

A

The dynamic load capacity is a value which has a unit of ‘N’ or’kN’ (Newtons or Kilo Newtons). The dynamic load capacity can be defined as the load that will give a life of one million revolutions of the inner race.

10
Q

Toughness

A

The ability of a metal to absorb energy and deform plastically before fracturing.

11
Q

Tensile test

A

A static test that measures the effects of a tensile force on a material.

12
Q

Compression test

A

Very common testing method that is uses to establish the compressive force or crush resistance of a material and the ability of the material to recover after a specified compressive force is applied and even held over a defined period of time.

13
Q

Ductility test

A

Is simply the strain to fracture

14
Q

Torsion test

A

A statice test that measures a materials resistance to shear.

15
Q

Static test

A

The load is applied slowly enough so that the speed of testing has a negligible effect on the results.

16
Q

Dynamic Tests.

A

The load is applied very rapidly and may Also be applied continuously or repeatedly.
