Gavin Fall 2018 1 Preliminaries This document describes the formulation of stiffness and mass matrices for structural elements such as truss bars, beams, plates, and cables(?). – The purpose of this paper is to use PAM-CRASH, a finite element analysis solver, to assess the performance of a mass production vehicle cross car beam (CCB) under an overlap frontal crash scenario (crashworthiness). The beam consists of a reflector and a driven element mounted to a boom consisting of two rigid arms, attached to the mast at the center. For phased array transducers, the maximum steering angle (at -6 dB) in a given case is derived from the beam spread equation. 6 Element OWA Yagi for 2 Meter Band.

The finite element solution of a beam element is a cubic polynomial while actual beam solution is of the 4 th order. This is for 4 elements.
