摘要： A method includes preparing a rocklike core sample for compressive testing, the rocklike core sample defining a longitudinal axis and having first and second axial ends. Preparing the rocklike core sample includes providing a throughhole in the rocklike core sample, the throughhole extending between a first opening at the first axial end and a second opening at the second axial end, wherein the first opening and the second opening are dimensioned differently. The rocklike core sample is mounted in a compressive testing apparatus, and a compressive test is performed on the rocklike core sample in the compressive testing apparatus. The compressive test includes compression in axial and radial directions. A related system includes a compressive testing apparatus and a sample preparation apparatus which prepares a rocklike core sample for compressive testing in the compressive testing apparatus, via providing a throughhole in the rocklike core sample.

摘要： Disclosed is a web-based tool for facilitating the inspection process for evaluating inspection items relating to assets at a site. A website is used to interface with the hand held devices used by inspectors in the field and create consistency in the way questions are posed, and recorded for inspection items. Unique identifiers are associated with each item so that they can be tracked. Also, a wireless camera arrangement is implemented where any photographs taken of a condition of a particular inspection item will automatically be incorporated into the form open regarding that item.

摘要： A method of designing a roller bearing is disclosed upon clarifying mechanisms of damage patterns in respect of two kinds of brinelling, involved in the bearing, wherein white-banded flaking (brittle flaking) is a plastic instability phenomenon appearing under high-speed deformation accompanied by adiabatic shear deformation status with the resultant occurrence of adiabatic shear band (also called white band) inside material of the bearing. This enables all of the damage patterns to be determined upon making comparison between shear strain and shear strain rate, occurring inside the bearing, and discriminated values.

摘要： The method involves measuring hydrogen permeation in the tubes by mass spectrometry, wherein the tube is inserted into a high or ultrahigh vacuum device in which a mass spectrometer and a total pressure gauge are located. H2 or H2 and inert gas mixtures are circulated inside the tube at the required partial pressure. The tube is then heated and the appearance of H2 outside the tube is observed. The flow thereof inside the tube and emergence time, called permeation time, are determined based on permeation curves. The emergence time of the first microcrack is also determined.

摘要： A stress corrosion crack test method for evaluating the stress corrosion crack susceptibility of a steel material in alcohol. The method includes filling a cell containing a uniaxial tensile test piece of the steel material with an alcohol solution containing carboxylic acid: 0.1 mmol/L or more and less than 40 mmol/L, chloride ions: 0.05 mg/L or more and less than 300 mg/L, and water: 0.1 vol. % or more and less than 5 vol. %. Additionally, the method includes applying a fluctuating stress at a frequency of 2.0×10−5 Hz or more and 2.0×10−2 Hz or less to the uniaxial tensile test piece in the tensile direction. The maximum stress being equal to or more than the yield strength and less than the tensile strength at a test solution temperature, and the minimum stress being 0% or more and 90% or less of the yield strength.

摘要： An apparatus and a method for simulating a mechanical stress applied to a sealant from a lightning strike upon an aircraft is provided. The apparatus comprises a specimen, a test fixture, and a capacitor. The specimen comprises an electrically non-conductive sealant for an aircraft fuel tank having a cylindrical shape, and an electrically conductive wire centered axially within the sealant. The test fixture secures the specimen during testing. The capacitor is electrically coupled to the test fixture, and simulates a lightning strike upon the aircraft by vaporizing the wire with a current to generate a mechanical shock to the sealant.

摘要： According to exemplary embodiments of the present invention, using a fracture limit stress line obtained by converting a hole expansion ratio into a stress as a criterion for a fracture, the risk of fracture in a material can be evaluated quantitatively by comparing the relationship between data obtained from a numerical analysis using a finite element method and the fracture limit stress line. Thus, when determining a fracture limit in a stretch flange portion in a thin plate in a process including one or more deformation path variations, it is possible to obtain the fracture limit curve easily and efficiently and predict the fracture with high accuracy, and the risk of fracture upon press forming or crash can be evaluated.

摘要： A mechanical test method prescribes compressing brittle balls in spherical conforming opposing platens producing equatorial bulging, tensile stresses, and resulting indentation crack growth that is imaged for providing direct measurement of the fracture toughness of brittle balls, such as, silicon-nitride balls used in hybrid bearings as well as conventional steel ball bearings, with measurement errors being immune to characterizing the dimensions and positioning of the precrack indentations, so that, the test method is accurate, repeatable, and robust.
