Development of an in-house MATLAB code for finite element analysis of composite beam under static load

The focus of this work is to develop an in-house finite element (FE) code using programming software, MATLAB for analysing composite beam subjected to tensile loading. The composite beams are modelled by using two dimensional quadrilateral plane elements. The computed results obtained from developed code are validated by experimentally as per standard ASTM D3039M-14 and commercially available finite element tool, ABAQUS (V2016). The fabricated composite beams made up of plain woven glass epoxy with eight plies using vacuum bag technique. The computed results obtained from in-house FE code are in good agreement with the experimental and ABAQUS simulated results. Further, the developed code has the capability to support post processing in the form of graphical representation.
