A Velocity Approach to Elasto-Plastic and Elasto-Viscoplastic Calculation by the Finite Element Method
(The American Society of Mechanical Engineers (ASME), 1990)A second order scheme for the time discretization of the elasto-plastic or elasto-viscoplastic behavior is proposed, based on a velocity approach. The complete set of equations is given for the ... -
Tool Face Temperatures in High Speed Milling
(The American Society of Mechanical Engineers (ASME), 1990)While it is now generally understood that in continuous chip forming processes such as turning, there is no magic high speed above which tool temperature decreases and tool life increases with ... -
A High Power, Sealed, Lead-Acid Battery for Electric Vehicles
(The American Society of Mechanical Engineers (ASME), 1990)A novel, lead-acid battery has been designed specifically for an electric van application. The design consists of horizontally oriented, dual lugged plates in a sealed configuration. Thin plates ... -
Mechanics of Kinking in Cables
(The American Society of Mechanical Engineers (ASME), 1990)Kinks or loops are formed in cables, subjected initially to torque and tension, in underwater and other applications due to a critical combination of torque and tension, resulting from sudden ... -

On-Line Detection of Drill Wear
(The American Society of Mechanical Engineers (ASME), 1990)An on-line system for drill wear detection has been developed by using a sensor fusion strategy. Both acceleration and thrust signals were analyzed. Flank wear area was used to evaluate drill ... -
Delamination During Drilling in Composite Laminates
(The American Society of Mechanical Engineers (ASME), 1990)Delamination is the major concern during drilling of composite laminates. Delamination, in addition to reducing the structural integrity of the laminate, also results in poor assembly tolerance ... -
Deep Drawing With Blank Holder Force Approximately Proportional to the Punch Force
(The American Society of Mechanical Engineers (ASME), 1990)A new method of applying blank holding force approximately proportional to the punch force in cup drawing is presented. An annular urethane pad compressed between two parts of a punch expands ... -
The Effect of Hardness on Residual Stresses in Orthogonal Machining of AISI 4340 Steel
(The American Society of Mechanical Engineers (ASME), 1990)Residual stress remaining in machined parts can be detrimental. Previous experimental evidence shows that hardness has a significant effect on its formation. Yet, no satisfactory explanation is ... -
An Approximate Model to Calculate Foldover and Strains During Cold Upsetting of Cylinders Part I: Formulation and Evaluation of the Foldover Model
