Temperature And Stress Distributions Produced In Long Circular Cylinders Cooled By Emission Of Thermal Radiation, Robert S. Pritchard
Temperature And Stress Distributions Produced In Long Circular Cylinders Cooled By Emission Of Thermal Radiation, Robert S. Pritchard
Mechanical Engineering ETDs
This study involves the determination of the temperature and stress distributions produced in long circumferentially symmetric circular cylinders cooled by emission of thermal radiation from the lateral surface. Temperature and strain responses obtained from an experimental model are presented for a set of parameters which correspond to the highest strain level which could be accurately determined with the strain gages. These responses are in good agreement with the results obtained by solution of an appropriate mathematical model. Temperature responses obtained from the same model, but having a higher initial temperature, are also presented and compared with analytical results. Reasonably good …
Cavity Effect In A Pressure Bar, Kenneth B. Simmons
Cavity Effect In A Pressure Bar, Kenneth B. Simmons
Mechanical Engineering ETDs
The investigation deals with certain aspects of wave propagation in a rod containing a penny-shaped cavity, particularly fracture related to the presence of the cavity. When a rod containing a cavity is subjected to a compressive stress pulse, part of the pulse is transmitted past the cavity and part is reflected. When the end of the rod is free, the cavity is subjected to a reflected tensile pulse which, if strong enough, can cause fracture. The existence of the cavity tends to weaken the rod since there is a reduction in the cross-sectional area and a stress concentration effect. Epoxy …
