AMCR TESTING AND INSPECTION Flashcards
2 types of testing
Destructive testing and Non-destructive testing
It is undertaken in order to understand a specimen’s performance or material behavior, these procedures are carried out to the test specimen’s failure. ________ procedures can either follow specific standards or can be tailored to reproduce set service conditions. It includes methods where the material is broken down in order to determine mechanical properties, such as strength, toughness and hardness.
Destructive Testing
It is used as part of a manufacturing or installation inspection to check if quality demands are being met. It’s a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or defects and discontinuities without causing damage to the original part.
Non-Destructive Testing
Types of Destructive Testing
Tensile Test
Compression Test
Bending Test
Torsion Test
Hardness Test
Hydrostatic Test
Charpy Impact Test
It also known as tension test, is probably the most fundamental type of mechanical test is performed on a material. These tests are simple, relatively inexpensive, and fully standardized. By pulling on something, you will very quickly determine how the material will react to forces being applied in
tension. As the material is being pulled, you will find its strength along with how
much it will elongate.
Tensile test
Method for determining behavior of materials under crushing loads. Specimen
is compressed, and deformation at various loads is recorded.
Compression Test
The flexure test method measures behavior of materials subjected to simple
beam loading. It is also called a transverse beam test with some materials.
Maximum fiber stress and maximum strain are calculated for increments of
load.
Bending Test
It measures the strength of any material against maximum twisting
forces. It is an extremely common test used in material mechanics to measure
how much of a twist a certain material can withstand before cracking or
breaking.
Torsion test
The most common uses for __________are to verify the heat treatment of a
part and to determine if a material has the properties necessary for its intended
use.
hardness tests
A tester that uses a hardened
spherical ball, which is forced into a
surface of the metal.
Brinell Tester
It measures the depth, and the hardness is indicated directly on a dial attached to the machine. Has two penetrator, a diamond cone and a hardened steel ball
Rockwell Tester
A portable unit designed for testing aluminum alloys,
copper, brass, or other relatively soft materials. It should not be used on aircraft
steels.
Barcol Tester
It is a test used to check leakage of weld joints, to determine axial and tangential strains of thick and thin cylinders by using strain gauges and strain meters.
Hydrostatic Test
a standardized high strain-rate test which determines the amount of energy
absorbed by a material during fracture. This absorbed energy is a measure of a given material’s notch toughness and acts as a tool to study temperature-
dependent ductile-brittle transition.
Charpy Impact Test
Types of Non-Destructive Test
Visual Inspection
Liquid Penetrant Inspection
Eddy Current Inspection
Ultrasonic Inspection
Acoustic Emission Inspection
Magnetic Particle Inspection
Magnaglo Inspection
Radiographic Inspection
Inspection of Composites
