At Westmoreland Mechanical Testing & Research, Inc Tension and Compression tests are conducted on an impressive range of machines with capacities from 10 grams to 1,000,000 lbs. Testing is conducted in various atmospheres (Argon, Vacuum, Corrosive Mediums) at cryogenic, ambient, and elevated temperatures (-450°F to +2200°F). Our proprietary testing software provides us with the capability to run standard tests plus full stress/full strain tests at various strain rates, crosshead speeds, load ranges, and strain ranges as your requirements demand.
The Mechanical Testing Labs at Westmoreland Mechanical Testing & Research, Inc test materials in accordance with customer specific specifications as well as all applicable ASTM Standard Test Methods. Our testing labs are accredited by both Nadcap and A2LA, as well as being approved by over 60 companies in the Aerospace, Nuclear, Automobile, and Medical fields.
In addition to standard size specimens, we have developed the expertise in preparing and testing round micro-size specimens (less than 0.005" thick).
Superior technology, responsive versatility, and quality performance ensures reliable and fast turnaround on all your test results.
The Mechanical Testing Labs at Westmoreland Mechanical Testing & Research, Inc perform destructive testing on a wide range of materials in accordance with all applicable ASTM Standard Test Methods in addition to testing to customer specific specifications.
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 subsize 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 also offers a line of Instrumented Impact Test designed to simulate real life rapid Energy absorption conditions caused by: falling objects, blows, collisions, drops, etc.
Drop-Weight Testing is preformed to ASTM E208. 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 or ASTM E292. 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 also can 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 at 75% of the yield strength to determine if the material is susceptible to hydrogen embrittlement.
The above 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, WMT&R has testing machines with ratios of 16:1 (6,000 lbs.) to 30:1 (30,000 lbs.)
