Mechanical Testing machines and equipment
"How much will that rubber band stretch?"
Mechanical testing refers to the testing of material properties by application of external forces. When you want to choose the proper materials, or test your product for quality assurance during product development, mechanical testing is where you begin.
Performing specific testing under correct conditions is the only way to ascertain that the materials truly perform the way your computer models have predicted. This is hands down the best way to avoid costly recalls and faulty products.

Which mechanical testing instruments are suited for you?
Our experts will always make sure you get the equipment you need. Still, it’s necessary for you to define the right testing parameters for your mechanical testing.
- Will you need 50 newtons of force, or 50,000 newtons?
- What conditions will the testing be performed in? Low temperature? High humidity?
- Will you need qualified personnel to operate the equipment?
- Do you need to perform several different tests, or just one type? Some testing equipment can do several types of tests.
Important fields of mechanical testing
Computers are unable to predict slight material defects within materials. Thus, computer generated models for predicting fatigue failures in parts under intense cyclic loading are notorious for their inaccuracy.
The purpose of fatigue testing is to determine, with real life applications, the point where cyclic loading will lead to noticeable structural damage and ultimately, structural failure.
The results yield invaluable data, such as:
- When, at earliest, will fatigue cracks or deformation appear?
- How long, after cracks become detectable to the human eye, will the crack grow before leading to structural failure?
The purpose of tensile testing is to find out how much force is required to pull an object apart. Ropes, wires and construction beams, among other things, must be intensely studied for tensile strength, as many other valuable material properties can be directly calculated when tensile strength is known. There are two key thresholds in tensile strength:
- When will a given material in a specific shape (let’s say a beam made of S355 grade structural steel) first start deforming when pulled?
- When will the object be unable to fully recover from the deformed state?
Material hardness refers to the ability to resist penetration. Tests are carried out with a diamond shaped sharp edge, which is pressed down towards the material surface with certain force. The depth of penetration is then measured, and a hardness value is calculated from the results.
Many surfaces, especially in consumer products, have high requirements for surface hardness for both performance and aesthetic reasons.
Compression testing is the opposite of tensile testing. Pressing on a material yields results on the amount of pressure the material can take before deforming. This method of testing is especially important for relatively long structures under heavy compression. Namely, columns in buildings and other structures. There are several important questions to answer regarding compression:
- At given free length, how much stress can be applied before structural stability is lost?
- How much stress can be applied before noticeable deformation occurs?
- How much stress can be applied to a part before deformation becomes permanent?
