Aluminum sheet effects in viscoelastic punching
This project was initiated to study the effects of the sheet metal on the process of punching circular holes with viscoelastic tooling. Two different kinds of aluminum sheet metal, each with four thicknesses were used ...
Punching aluminum sheet with rubber press pads
Rubber pads can be employed to cut or form sheet metals when acted upon by high pressures in conjunction with suitable tooling. This phenomenon has been incorporated into a production technique known as the Guerin process. ...
Elastic properties of anhydrite
The elastic constants of the mineral anhydrite (CaSO4), which belongs to the orthorhombic crystal system, were unknown prior to this investigation. It was the main object of this thesis to investigate and measure these ...
The Development of a High Pressure Pulsating Flow Hydraulic Servomechanism
Pulsating flow 9p.f.) hydraulic control systems offer a number of unique advantages over conventional direct or continuous flow (c.f.) systems. These advantages make pulsating flow control particularly useful and desirable ...
A FLUIDIC CONTROL SYSTEM APPLIED TO ROCKET PAYLOAD ROLL CONTROL
The problem of automatic roll control of a partial payload of an upper atmosphere sounding rocket is discussed. A control system is proposed for accomplishing this function which is entirely fluidic, from sensing the ...
Effects of surface finish on the fatigue life of "cold-rolled" mild steel specimens
In the first part of this investigation, the Krouse rotating beam fatigue machine and the R. R. Moore rotating beam fatigue machine were compared. On the basis of determining the fatigue life of cold-rolled steel at one ...
