Abstract
Analysis of composite materials, especially the estimation of elastic properties is a tedious job considering the number of parameters that govern the behaviour of materials. Hence automation of variation of this variable is suggested. In the present work, a FE based interface tool named VTUMAT is developed. VTUMAT at present interfaces with Abaqus/Standard for generating the RVE of the composite material and for visualising the stress and strains induced in the RVE*. The accuracy of VTUMAT is verified by comparing the results obtained from it with the result of Rule of Mixture. It is found that VTUMAT results match closely with the theoretical results.
