A model was developed to predict the burst pressure of the copper tube. The assumption for the model is based on plane strain plastic deformation to an instant of instability where differential internal pressure is equal to zero. Physical simulations were used to develop a relevant microstructure that is representative of the tube in a manufactured heat-exchanger. To this end, cold rolling was used to simulate post-extrusion straightening and sizing of the tube. A subsequent thermal treatment was performed in a tube furnace to simulate a brazing thermal cycle. Tensile tests were conducted to obtain material data, and to determine material constants for a Voce type constitutive equation. Burst tests were conducted to validate the predictive model. Burst pressures were predicted to within 6% of measured values. The effects from cold working and the simulated brazing cycle were also evaluated in this research. 2013 English text Ohio University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1381328798 http://rave.ohiolink.edu/etdc/view?acc_num=ohiou1381328798 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
