Tensile Properties

Reduction of area is the change in cross-sectional area divided by the original cross-sectional area.This change is measured in the necked down region of the specimen.Like elongation,it is usually expressed as a percentage.As previously discussed,tension is just one of the way that a material can be loaded.Tensile Mechanical Properties of Miniature SizeSpecimen Size Effect on Mechanical Properties Table 2 and Fig.5 show the effect of specimen size on mechanical properties.Fig.5 (a) depicts relationship between specimen size and tensile strength.Tensile strength of the miniature size specimen ( =5mm) are almost same as that of the bulk type specimen ( =10mm) for Sn-3.5Ag lead-freeSpecimens size,aggregate size,and aggregate type effect Specimens with 14mm maximum aggregates size did not exhibit consistent aggregate size effect when compared with the 7mm and 20mm maximum aggregate size specimens with nominal spalling depths of 18.88 mm and 59.06 mm for specimens LP14B and LP14G as shown in Table 3.
