4. Numerical analysis and results
Based on the above accuracy and efficiency analyses, the present
developed meshfree boundary-domain integral equation
method combination with these four kinds of time stepping integral
algorithms are employed to analyze the forced vibration
response of the FG cantilever beams subjected to the external
excitation force P¼1,000,000 g(t), with two different load cases
(1) a harmonic load (g(t)¼sin(ωt)), and (2) a transient load (g(t)¼
1.0, 0rtr0.5; g(t)¼0.0, t40.5). The FG cantilever beams are
composed by steel and aluminum obey an exponential law described
as bellow
