چکیده انگلیسی
Structural dynamics applications feature a particular type of second order stiff equations, often in combination with low smoothness of the right side, large dimension and non-linear forcing terms. As alternative to implicit schemes, explicit Runge-Kutta-Nyström methods are analysed, with focus on low order and maximized stability domain since spurious high frequency oscillations need not be resolved. It turns out that it is possible to construct methods with a stability domain that stretches up to hÏ=2s on the imaginary axis where h is the stepsize, Ï the largest frequency in the system, and s the stage number. Simulation examples generated by FEMLAB show that the methods are competitive.
