  2. Standard penetration test - Wikipedia

    en.wikipedia.org/wiki/Standard_penetration_test

    Symbol used in drawings Standard penetration test N values from a surficial aquifer in south Florida. The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed ...

  3. Nippon Screw Weight System - Wikipedia

    en.wikipedia.org/wiki/Nippon_Screw_Weight_System

    NSWS can measure very soft zones, converted N-value of zero in the ground that had been considered difficult. It has 1.08 cm interval.SPT conducts the test every 50 cm, and 30 cm interval out of 50 cm is tested so the rest, 20 cm, is not measured; that means 40% of an entire hole is unknown. NSWS does not suffer from such a limitation.

  4. Spt function - Wikipedia

    en.wikipedia.org/wiki/Spt_function

    The spt function (smallest parts function) is a function in number theory that counts the sum of the number of smallest parts in each integer partition of a positive integer. It is related to the partition function. [1] The first few values of spt(n) are: 1, 3, 5, 10, 14, 26, 35, 57, 80, 119, 161, 238, 315, 440, 589 ... (sequence A092269 in the ...

  5. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    One advantage of CPT over the Standard Penetration Test (SPT) is a more continuous profile of soil parameters, with data recorded at intervals typically of 20 cm but as small as 1 cm. Manufacturers of cone penetrometer probes and data acquisition systems include Hogentogler, which has been acquired by the Vertek Division of Applied Research ...

    en.wikipedia.org/wiki/Talk:Standard_penetration_test

    The first 10cm layers has N-value of 3 so if there were a 30cm layer with N-value of 3, the SPT can reach the bottom of the layer with three blows, and the first should stop at 10cm depth. This is what I mean by that the first layer has N-value of 3. The middle layer is empty, and the bottom layer has N-value of 3 as well.

    The new value is the mean atmospheric pressure at an altitude of about 112 metres, which is closer to the worldwide median altitude of human habitation (194 m). [ 10 ] Natural gas companies in Europe, Australia, and South America have adopted 15 °C (59 °F) and 101.325 kPa (14.696 psi) as their standard gas volume reference conditions, used as ...

  9. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    Most metals have an -value between 0.10 and 0.50. In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [ 1 ] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
