Material Characterization of Hybrid Composite: Experimental Using Strain Gauge/DIC with Finite Element Modelling Macro/Micro Scale

Abstract:

The study presents the multi methods of determining mechanical properties and mechanical characterization under tensile loading of hybrid composite in the form of experimental technique involving measurement of strain using strain gauge and digital image correlation (DIC) technique utilizing open source platform Ncorr to compute the strain on surface of hybrid composite. The method of micro mechanical modelling using Finite Element Modelling (FEM) in the mode of representation volume element (RVE) method and macro scale FEM using commercial software Ansys have been performed to compute the modulus of elasticity in direction of uniaxial tensile loading. The four methods then compared which yields very consistent results with each other. It is observed that all four methods are reliable in determining mechanical properties of unidirectional single composite as well as hybrid composite. The experimental involved the use of ASTM D3039 standard tensile test for hybrid composite and strain are measured using strain gauges and DIC.
