This is the most widely used IFC format, having the advantage of compact size yet readable text. IFC-XML is an XML format defined by ISO 10303-28 ("STEP-XML"), having file extension ".ifcXML". This format is suitable for interoperability with XML tools and exchanging partial building models.
The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point bending configuration. The test is named after the English engineer Edwin Gilbert Izod (1876–1946), who described it in his 1903 address to the British Association , subsequently published in ...
According to ASTM A370, [12] the standard specimen size for Charpy impact testing is 10 mm × 10 mm × 55 mm. Subsize specimen sizes are: 10 mm × 7.5 mm × 55 mm, 10 mm × 6.7 mm × 55 mm, 10 mm × 5 mm × 55 mm, 10 mm × 3.3 mm × 55 mm, 10 mm × 2.5 mm × 55 mm. Details of specimens as per ASTM A370 (Standard Test Method and Definitions for ...
A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...
The publication describes requirements, levels and test methods to achieve immunity compliance of an electronic product. The purpose is to create a reproducible ground for product compliance and the standard defines: ranges, levels, test equipment, setups, procedures, calibrations, generator waveforms and general uncertainties.
The stress intensity factor at the crack tip of a compact tension specimen is [4] = [() / / + / / + /] where is the applied load, is the thickness of the specimen, is the crack length, and is the effective width of the specimen being the distance between the centreline of the holes and the backface of the coupon.
A common variation on the IFC structure is to replace the leading ISO 3166-1 alpha-2 letters with their numeric equivalents. The publisher's code is then prefixed with leading zeros and the dot is excluded to create a 13 digit code. This allows the IFC to be used as a unique numeric code for UPC-A barcodes or other numeric systems.
where is the size of the contact region between the indenter and the sample, and is the sample’s elastic modulus. Typical atomic-force microscopy (AFM) cantilevers have k machine {\displaystyle k_{\text{machine}}} in the range 0.05 to 50 N/m, and probe size in the range ~10 nm to 1 μm.
