WMT&R Mechanical Testing Includes:
Charpy Impact Test
IZOD Impact Test
Double Shear Test
Hydrogen Embrittlement Test
Static Notch Testing
Dynamic Tear Testing
Impact Testing most commonly consists of Charpy and IZOD Specimen configurations. The Charpy tests are conducted on instrumented machines capable of measuring less than 1 foot-pound to 300 foot-pounds at temperatures ranging from -320°F to over 2000°F. Specimen types include notch configurations such as V-Notch, U-Notch, Key-Hole Notch, as well as Un-notched and ISO (DIN) V-Notch, with capabilities of testing sub-size specimens down to ¼ size. IZOD testing can be done up to 240 foot-pounds on standard single notch and type-X3 specimens.
Westmoreland Mechanical Testing & Research, Inc (WMT&R) offers a line of Instrumented Impact Tests designed to simulate real life rapid energy absorption conditions caused by falling objects, blows, collisions, drops, etc. A part or material's ability to resist impact often is one of the determining factors in the service life of a part, or in the suitability of a designated material for a particular application. Impact resistance can be one of the most difficult properties to quantify. The ability to quantify this property is a great advantage in product liability and safety. These mechanical tests are performed on round or flat specimens with gage lengths ranging from ½ inch to 2.0 inches. Anticipating the need to accommodate various specimen sizes, Westmoreland Mechanical Testing & Research, Inc (WMT&R) has testing machines with ratios of 16:1 (6,000 lbs.) to 30:1 (30,000 lbs.)
Drop-Weight Testing is preformed to ASTM E208-Standard Test Method for Conducting Drop-Weight Test to Determine Nil-Ductility Transition Temperature of Ferritic Steels. This test is conducted to determine the nil ductility transition temperature (NDT) of materials. Tests can also be conducted to your temperature requirements from elevated temperature down to -320°F.
Dynamic Tear Testing has a wide range of research and development applications. Used to study the effects of metallurgical variables like heat treatment, composition, and processing methods on the dynamic tear fracture resistance of material. Manufacturing processes, such as welding, can be effectively evaluated for their effect on dynamic tear fracture resistance. Additional uses for this test include evaluating the appropriateness of selecting a material for an application where a baseline correlation between Dynamic Tear energy and actual performance has been developed.
Stress and Creep Rupture Tests are conducted at temperatures up to 2200°F to either ASTM E139-Standard Test Methods for Conducting Creep, Creep Rupture and Stress Rupture Tests of Metallic Material or ASTM E292-Standard Test Method for Stress Rupture Combination. Temperature and creep readings are continuously monitored and recorded digitally to ensure utmost accuracy. The creep test program is capable of recording strain readings up to 120 times per hour. This data is utilized to maintain temperature tolerances during the test, and to create a unique temperature history report. The reduced section of a creep test specimen can also be strain-gaged as a means of measuring the amount of strain during testing.
Stress and Creep Rupture Tests can also be conducted in environments under vacuum, corrosive, or inert atmospheres. Maximum temperatures for these tests exceeds 1700°F and are usually performed on materials that exhibit excessive corrosion at elevated temperatures in an air environment.
Cyclic Rupture Testing is designed to load and unload a test specimen at certain time intervals. The test temperatures range from room to +2200°F. Prior to starting a test, four strain gages are attached to a test specimen to ensure that bending strains are within specified requirements.
The Static Notch Test is performed at room temperature under a constant load for a minimum of five hours to determine if the material is notch sensitive at room temperature.
The Embrittlement Relief Test is also performed at room temperature, but for 200 hours under a load of some percentage of either the yield strength or ultimate tensile strength. Typically, this test is conducted in accordance with ASTM F519-Standard Test Method for Mechanical Hydrogen Embrittlement Evaluation of Plating/Coating Processes & Service Environments at 75% of the yield strength to determine if the material is susceptible to hydrogen embrittlement.
