Non-dimensional temperature of the middle node versus non-dimensional time for the three cases in table 1. The melting temperature corresponds * T�1, and time is scaled by the input current pulse period values in table 1. to We divided the quantity in equation 31 by 30 for the load step time in ANSYS, to insure approximately 30 load steps at which the program would calculate a solution leading up to the * melting point of the center node of the bridge wire. Once a load step was reached where T�1 for this node, we halted the solution and used a linear interpolation with the previous load step to approximate the exact time at which the temperature of this node exceeded the melting temperature. 9
