MECHANICAL TESTING OF METAL & NON-METALLIC MATERIALS

From raw materials to finished products, IMR's mechanical testing group offers a wide range of testing to evaluate metals, polymers, composites and finished products. Whether you need routine tensile testing or a more complex multi-stage fatigue program, we are equipped to provide the answers you need. Most testing is completed in three days or less for routine tensile, hardness and Charpy impact testing.  More complex tests like hydrogen embrittlement, dynamic mechanical analysis (DMA) and weld testing are handled in a timely manner, complete with thorough analyses.

Our fatigue testing frames allow us to simulate various use environments in high and low cycle mode. These frames also enable us to perform fracture toughness and crack growth experiments. With capacities to run comprehensive test plans from -320°F to 1800°F, we can perform HCF (High Cycle Fatigue) and LCF (Low Cycle Fatigue) testing and analysis of hot section gas turbine components and other high temperature applications.

 

Creep and Stress Rupture 

creep-stress-rupture-crop-300

These tests are designed to evaluate the ability of a part or material to safely hold a load and are critical to manufacturers in a wide range of industries including aerospace and power generation among others.


 

Fatigue Testing sERVICES

high-temp-375

The test frame's ability to expose the test specimen to temperatures up to 1800°F can replicate the service conditions experienced by turbine blades in gas engines, power generating plants, and jet engines.


 

Tensile Testing

TensileBars_0

Tensile testing, also known as pull testing, is a standard test where a sample is placed in grips and subjected to a controlled tension until it fails. This provides information about materials including ultimate tensile strength, yield strength, elongation, and reduction in area.  


 

Fracture Mechanics

fracture-mechanics-450

Fracture mechanics calculates the relationship between applied loading, environmental factors, the presence of cracks and crack-like defects, and the inherent properties of the material used in components to prevent failure in-service.


 

CHARPY IMPACT  

charpy samples

This test provides information on the material's ductility, as well as the temperature-dependent ductile-brittle transition.  Ductile vs. brittle fracture can be compared by looking at the flat planes (brittle) and the jagged edges (ductile) to estimate a percentage of each.


 

Hardness Testing

Hardness

Hardness testing is a basic test used to verify raw materials or as a quick check for materials that fail or aren't performing as expected.  Hardness tests quantify the resistance of a material to plastic deformation and is available as microindentation or macroindentation.


 

Bond pull testing

bond-pull

Bond pull testing accurately measures bond strength, as well as evaluating bond strength distributions. This helps define the reliability of bonds under stress conditions, like thermal cycles, vibration and shock.

ENGINEERING / R&D SUPPORT

young engineers-stock

Companies have turned to IMR for engineering and R & D support to relieve their engineering groups from running tedious test programs.  This assistance allows their teams to more effectively focus on the application of test results to their new products.

Weld Qualification 

welding sample 1-375

Welder qualification and weld evaluation for OEM's and vendors. Qualification to the AWS, European Directive, and ASME standards can involve visual,  impact, macroetch, tensile and bend testing.
