Analysis of Tube Extrusion
(The American Society of Mechanical Engineers (ASME), 1970)Two solutions for the detailed mechanics of tube extrusion are presented. One is based on the theoretical velocity field, and the other on the flow field observed experimentally. The theoretical ... -
Deformation Characteristics and Ductile Fracture of 1040 Steel in Simple Upsetting of Solid Cylinders and Rings
(The American Society of Mechanical Engineers (ASME), 1970)Experiments were conducted involving the upsetting of solid cylinders and rings of annealed SAE 1040 steel at room temperature for various end conditions. Measurements were made on the displacement ... -
Effect of Resilient Mounts on Surface Finish and Machining Accuracy
(The American Society of Mechanical Engineers (ASME), 1970)External disturbances, as well as internal ones, cause a relative motion between the cutter and workpiece and thereby influence detrimentally the surface finish and machining accuracy. By properly ... -
The Development of a New Design for Railroad Flatcar to Carry Cargo Containers and Highway Trailers Interchangeably
