In this paper, the dynamic fracture toughness test of 2A12T4 aluminum alloy compact tension (CT) specimens is carried out by tensile stress waves, based on a Hopkinson experimental device. The crack propagation of the CT specimen is recorded by a high-speed camera. The dynamic fracture toughness of CT specimens with two different crack forms was studied by using the digital image correlation method...
A major advantage of the powder metallurgical (P/M) manufacturing process is its ability to shape powder directly into a final component with a primary goal of a high quality, homogeneity of density and mechanical properties and productivity. In this research, powder die filling, powder transfer and powder compaction process have been studied in succession using a novel experimental set-up that utilizes...
