Test Methods for Conducting Time for Rupture Notch Tension Tests of Materials

ASTM E143-01 室温下剪切模量的标准试验方法

1.1 This test method covers the determination of shear modulus of structural materials. This test method is limited to materials in which, and to stresses at which, creep is negligible compared to the strain produced immediately upon loading. Elastic properties such as shear modulus, Young''s modulus, and Poisson''s ratio are not determined routinely and are generally not specified in materials specifications.

ASTM E646-00 金属薄板材料拉伸应变硬化指数(N-值)的标准试验方法

This test method is useful for estimating the strain at the onset of necking in a uniaxial tension test (1). Practically, it provides an empirical parameter for appraising the relative stretch formability of similar metallic systems. The strain-hardening exponent is also a measure of the increase in strength of a material due to plastic deformation. The strain-hardening exponent may be determined over the entire plastic stress-strain curve or any portion(s) of the stress-strain curve specified in a product specification. Note 38212;The strain interval 10–20% is commonly utilized for determining the n-value of formable low carbon steel products. This test method is not intended to apply to any portion of the true-stress versus true-strain curve that exhibits discontinuous behavior; however, the method may be applied by curve-smoothing techniques as agreed upon. Note 48212;For example, those portions of the stress-strain curves for mild steel or aluminum alloys which exhibit yield-point elongation or Luuml;ders bands may be characterized as behaving discontinuously. Note 58212;Caution should be observed in the use of curve-smoothing techniques as they may affect the n-value. This test method is suitable for determining the tensile stress-strain response of metallic sheet materials in the plastic region prior to the onset of necking. The n-value may vary with the displacement rate or strain rate used, depending on the metal and test temperature.1.1 This test method covers the determination of a strain-hardening exponent by tension testing of metallic sheet materials for which plastic-flow behavior obeys the power curve given in the Introduction. 1.2 This test method is for metallic sheet materials with thicknesses of at least 0.005 in.

Standard Test Method for Comparing Metal Removal Fluids Using the Tapping Torque Test Machine

ASTM E1875-00e1 利用回声共振测试动态杨氏模量、剪切模数和泊松比的标准试验方法

This test method has advantages in certain respects over the use of static loading systems for measuring moduli. 5.1.1 This test method is nondestructive in nature. Only minute stresses are applied to the specimen, thus minimizing the possibility of fracture. 5.1.2 The period of time during which measurement stress is applied and removed is of the order of hundreds of microseconds. With this test method it is feasible to perform measurements at high temperatures, where delayed elastic and creep effects would invalidate modulus measurements calculated from static loading. This test method is suitable for detecting whether a material meets specifications, if cognizance is given to one important fact in materials are often sensitive to thermal history. Therefore, the thermal history of a test specimen must be considered in comparing experimental values of moduli to reference or standard values. Specimen descriptions should include any specific thermal treatments that the specimens have received.1.1 This test method covers the determination of the dynamic elastic properties of elastic materials. Specimens of these materials possess specific mechanical resonant frequencies that are determined by the elastic modulus, mass, and geometry of the test specimen. Therefore, the dynamic elastic properties of a material can be computed if the geometry, mass, and mechanical resonant frequencies of a suitable test specimen of that material can be measured. Dynamic Young''s modulus is determined using the resonant frequency in the flexural mode of vibration. The dynamic shear modulus, or modulus of rigidity, is found using torsional resonant vibrations. Dynamic Young''s modulus and dynamic shear modulus are used to compute Poisson''s ratio. 1.2 This test method is specifically appropriate for materials that are elastic, homogeneous, and isotropic (1). Materials of a composite character (particulate, whisker, or fiber reinforced) may be tested by this test method with the understanding that the character (volume fraction, size, morphology, distribution, orientation, elastic properties, and interfacial bonding) of the reinforcement in the test specimen will have a direct effect on the elastic properties. These reinforcement effects must be considered in interpreting the test results for composites. This test method is not satisfactory for specimens that have cracks or voids that are major discontinuities in the specimen. Neither is the test method satisfactory when these materials cannot be fabricated in a uniform rectangular or circular cross section.1.3 A high-temperature furnace and cryogenic cabinet are described for measuring the dynamic elastic moduli as a function of temperature from -195 to 1200oC.1.4 Modification of this test method for use in quality control is possible. A range of acceptable resonant frequencies is determined for a specimen with a particular geometry and mass. Any specimen with a frequency response falling outside this frequency range is rejected. The actual modulus of each specimen need not be determined as long as the limits of the selected frequency range are known to include the resonant frequency that the specimen must possess if its geometry and mass are within specified tolerances.1.5 There are material specific ASTM standards that cover the determination of resonance frequencies and elastic properties of specific materials by sonic resonance or by impulse excitation of vibration. Test Methods C215, C623, C747, C848, C1198, and C1259 may differ from this test method in several areas (for example; sample size, dimensional tolerances, sample preparation). The testing of these materials shall be done in compliance with these material specific standards. Where possible, the procedures, sample specifications, and calculations are consistent with these test methods. ......
