The rules regarding the propagation of irreversible phase boundaries along a finite rod are investigated with a phase transition constitutive model based on the simple mixture theory.

Using finite element analysis method, three-dimensional calculation is conducted for force summing on rod in high-inclination well of Liaohe tidal zone oilfield.

This paper gave the computer simulation of natural frequencies and vibrational modes of truck frames, based on the structural features of the frame, by finite element method of thin wall rod system.
