Free vibration occurs without external forces after initial disturbance, governed by the mass-spring system dynamics.
Natural frequency and time period are fundamental properties influencing system oscillation in free vibration.
Real-world structures often experience damping, which alters vibration behavior critical to earthquake-resistant design.
The motion of a mechanical system allowed to vibrate naturally after an initial disturbance, without external forces.
The frequency at which a system naturally oscillates, determined by the mass and stiffness in an SDOF system.
The effect of energy dissipation in a system that leads to a decrease in the amplitude of oscillation.
A phenomenon where a system vibrates with maximum amplitude at its natural frequency, often resulting in structural failure.
A measure of damping in systems that quantifies the rate of amplitude decay over time.
