Abstract
This paper puts forward a new method of optical non-contact measurement in the necking process of material tensile test. By the scanning of polygonal prism and the linear array CCD we can measure the whole dynamical process, which includes the change of the necking position and the necking quantity with the gradually applied load. The results prove that this method makes the mechanical property of material described more accurately and the use of material more optimization.
