Finite Element for Timoshenko Beam Based on Mechanical Impedance.

Abstract

A finite element model for representation of a Timoshenko beam segment is derived. The model is a massless beam, having bending and shear flexibility, carrying concentrated masses on rigid arms to account for translatory and rotary inertia. The accuracy of the model is domonstrated by comparing its impedance and ground shock response to those of the exact Timoshenko beam, the exact Bernoulli-Euler beam, and center-of-gravity lumped mass models.
