Performance tests of wire strain gages 3: calibrations at high tensile strains (open access)

Performance tests of wire strain gages 3: calibrations at high tensile strains

Report presenting results of calibration in axial tension over the strain range 0 to 0.03 are presented for 15 types of single element, multistrand wire strain gages. Considerable nonlinearity was observed at strains between 0.0025 and 0.006. Fifty-eight percent of the gages failed by breaking of the strain-sensitive wire at strains less than 0.03.

Column Strength of Extruded Magnesium Alloys AM-C58S and AM-C58S-T5 (open access)

Column Strength of Extruded Magnesium Alloys AM-C58S and AM-C58S-T5

"Tests have previously been made to determine the column strength of magnesium alloy AM-C58S-T5 extruded rod, but these few data were not considered a satisfactorily wide basis for establishing a general formula for the column strength of this alloy. It was therefore decided to make additional tests on a number of extruded sections of magnesium alloy AM-C58S-T5 with some tests on AM-C58S for comparison" (p. 1).
