Tensile Testing

Tensile TestingTensile Testing

Tensile testing, also known as tension testing is a fundamental test in which a sample is subjected to a uniaxial tensile load until failure.

The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. Properties that are directly measured via a tensile test are ultimate tensile strength, yield strength, maximum elongation and reduction in area.

Charpy/Izod Impact Testing

An impact test measures the energy absorbed by a standard notched specimen while breaking under an impact load.

The impact test continues to be used as an economical quality control method to determine the notch sensitivity and impact toughness of engineering materials.

Hardness Testing (Vickers, Brinell & Rockwell)

Indentation hardness tests are used to determine the hardness of a material to deformation.

Several such tests exist, wherein the examined material is indented until an impression is formed; these tests can be performed on a macroscopic or microscopic scale.

Metallurgical Investigations and Failure Analysis

Metallurgical Investigations

MecTest provides independent expert opinions regarding material failure.  Our metallurgical engineers examine and test materials to evaluate the root cause of your product failure.

Investigations include:

  • Root cause failure analysis determination
  • Photographic documentation
  • Failure mode identification
  • Fracture evaluations
  • Identification of defects

Failure Analysis Investigation

Failure of a component could be slow or a sudden total failure.

Typical Root Cause Failure Mechanisms are:

  • Fatigue failures
  • Corrosion failures
  • Stress corrosion cracking
  • Ductile and brittle fractures
  • Hydrogen embrittlement
  • Creep and stress rupture

Hydrostatic testing

A hydrostatic test is a way in which leaks can be found in pressure vessels, cylinders, pipelines etc. The test involves placing water, in the pipe or vessel at the required pressure to check for leaks. Hydrostatic testing is an economical way of verifying new products and monitoring in service products to ensure safe operation.

 

 

Macro examination, Bend tests, Fillet-break, Nick-break tests and Flattening tests

These tests are usually supplementary to other tests such as those referred to above and or Non Destructive Testing. These tests do not provide any direct numerical result but are very reliable to expose and identify discontinuities that may be considered unacceptable according to requirements of an application standard or as a quality control process.

 

In-Service Pressure Equipment Inspection

In-service pressure equipment inspection is performed in accordance with AS/NZS 3788. We can assist with all regulatory inspections, installations, repair and design verification.
