成果简介	NOVELTY - The method involves using Timoshenko and Euler-Bernoulli beam theories to compute deflection and rotation under no external loading conditions. The differential equations governing free transverse vibrations in beams are derived, incorporating material properties Young's modulus and shear coefficients. The damping ratio of a cantilever beam is computed using the Half-Power Bandwidth Method (HPBM) based on transfer function amplitude. The frictional energy loss and its impact on vibration dynamics are highlighted. The effect of beam length is evaluated on damping ratios, showing increased damping capacity with longer beams due to higher dynamic slip and micro-slip energy loss. USE - Method for determining free transverse vibrations in cantilever beams using Timoshenko and Euler-Bernoulli beam theories to compute deflection. ADVANTAGE - The method enables reducing the dynamic slip and energy loss, and increasing the static bending stiffness of the riveted short cantilever beam, thus increasing the damping capacity of the joint, and hence reducing the frictional energy loss and reducing the input strain energy. The method allows the joint to be fabricated in a simple and cost effective manner, and reduces the number of layers, thus reducing the manufacturing cost of the joints.
