The maximum in current corresponds to the half of wavelength interval due to the formation of standing wave between source and plate.[r]

Thestress is determined by dividing the load values bythe original cross-sectional area of the specimen.The elongation is measured by determining theamounts that two reference points on the specimenare moved apart by the action of the machine.

geometry of the interlacing point. He set the interlacing point in space, presented it as a space curve, and researched how the fabric behaves when forces act upon it and what deformations occur (Kawabata, 1989).

During high temperature welding, some surrounding metal may be elevated tobetween 500°F and 1000°F. In this temperature region, the austenite is transformed into a body-centered cubic lattice str[r]
