Study of Asymmetric Elastic Beams in Off-Axis Four-Point Bending
The intention of this paper is to study the mechanical behavior of asymmetric elastic beams in off – axis four point bending. The overall phenomenon is investigated for high rates of the curvature. An approximate analytical method to estimate the deflection is proposed, rendering it expressible in terms of a finite combination of elementary single – valued functions. The novel element here is the examination of the elastic behavior of the continuum beam without its separation in distinguished regions. Hence, the derived analytical representation of the deflection concerns both its positive and negative rates. Consequently, the proposed explicit solution enables us to draw firm qualitative information about a large category of rectangular continuum beams.
