Bending Analysis of a Finite Beam on a Reinforced Halfplane

Abstract

This paper deals with an experimental study, using the photoelastic method, on the bending analysis of a centrally loaded finite free-free beam resting on a partly reinforced (horizontally) elastic halfplane. in the experimental study the interface between the beam and partly reinforced halfplane has been made both frictionless and fully bonded. an experimental-numerical hybrid method, developed earlier by the authors has been used to determine the contact pressure distribution. the contact pressure distribution thus obtained has been compared with the results obtained using an analytical-numerical procedure in which two different modellings have been used for the reinforced region viz., (i) equivalent orthotropic (composite approach); and (ii) layered system (discrete approach). Results of contact pressure distribution as well as bending stress distribution in the beam have been presented for several cases. the experimental procedure presented here is easy to apply to such complex practical problems and could be of interest to design engineers.
