According to the kinetic equation derived from the linear theory of elasticity, the closer the applied frequency is to the resonant frequency of the system (e.g. cantilever), the amplitude will approach infinity. According to the simulation of COMSOL, the simulation of the Euler beam is in line with this law, but when I use the finite element simulation and find that the amplitude at the resonant frequency is finite, what I want to know is what method is used for the amplitude at the resonant frequency derived by the finite element? How is it different from the kinetic equations derived using linear theory? Is it nonlinear theory?
