| Abstract: | The transient temperature fields generated by a pulsed laser in two-layered Ni-film and Al-substrate cylindrical pipe are obtained by using the finite element method.The temperature dependences of material properties are taken into account during the numerical simulation.The temperature distribution of Ni-film and Al-substrate are obtained in angular orientation at various time.It will be useful in the research on thermo-elastic excitation of laser ultrasonic in two-layered film-substrate cylindrical systems. |

| Keywords: | laser ultrasonic film-substrate transient temperature field finite element method. |
