-covered areas; performing calculation through an online flatness calculation formula to obtain compensated flatness detection values of the flatness measuring areas according to the stress values when all the total sensing areas of the flatness measuring areas are completely covered by the strip steel....
Hello, What formula would I need to use in excel for this as excel doesn't calculate 0.35% using this formula =a1*b1+c1 Ie 15,332.92 *...
Also during this test a change of temperature produces a change of pressure because the thermal expansion coefficient of water is larger than that of steel. After such a strength test the container must become completely dry before performing the leak test with gas filling. A small leak can ...
;CONSTITUTION: Sound velocities Vm, V are measured for a specimen, i.e., a steel member, and a cast item and carbon content C is inputted together with the hardness HB of the specimen. An index value α' is then calculated according to an experimental formula based on the ratio V/Vm ...
