Mechanical Testing

How strong is it? Will it resist wear? Is it likely to crack when being stamped? These are some of the questions that can be answered by testing the mechanical properties of your material.mechanical testing

At Paragon Systems Testing Lab, we have all the state of the art equipment required to conduct extensive mechanical testing to measure hardness, tensile strength, elongation, elasticity, and fatigue limit.

Tensile and Formability Testing

A variety of materials properties can be determined from a tensile test. The yield strength is the stress per unit area that a material can withstand before permanent deformation occurs. The ultimate tensile strength is the maximum stress per unit area that a material can withstand before rupture. Both materials properties, which are determined from a tensile test are used in design calculations as well as routine quality control.
Ductility is measured using elongation and reduction of area.

The strain hardening test (n-value) and the plastic strain ratio (r-value) are used as measures of formability and are useful measurements for deep drawing or stretch forming applications.

The existence of hydrogen embrittlement damage can be determined with a static load tensile test. This test is commonly used to verify safe plating conditions were present when plating hardened steels.

Most tensile materials properties can be determined at temperatures ranging from -70°C to 200°C.mechanical testing

Hardness Testing

We can perform all of the common indentation hardness tests for metal, plastic and rubber materials.

Both macro hardness testing techniques like Rockwell or Brinell and micro techniques like Vickers or Knoop are accurately determined with our modern digital equipment.mechanical testing

The Rockwell or Barcol hardness test method can also be used on plastic and composite materials while the Durometer method is usually employed on rubber or elastomeric materials.

Flexural Testing

Flexural materials testing is used to characterize the properties of a material loaded in bending.

Depending on the method selected, the two loading conditions are a beam in 3-point or in 4-point bending.

A variety of materials properties are defined by the flexural test methods but the two properties most commonly determined are flexural modulus and flexural strength.mechanical testing

Flexural modulus is a measure of the initial stiffness of the material in bending while flexural strength describes the ultimate stress that the material can support in bending.

Flexural materials properties can be determined at temperatures ranging from -70°C to 200°C.mechanical testing
