Fracture Test & Fracture Parameters of Self Compacting Concrete using ANSYS

Abstract

This paper presents a nonlinear finite element modeling and analysis of Self Compacting Concrete (SCC) beam subjected to three point bending load. In this study, the beam was modeled using ANSYS Workbench 17.2 nonlinear finite element software. The concrete is modeled using ‘SOLID65’- which is capable of simulating the cracking and crushing behaviour of brittle materials. Grade of concrete used was M40 for the beam. The beam had an overall dimension of 430×150×100 mm. The beam is studied for the ultimate load, load-deflection and load-strain behaviour for this case and compared with the available experimental values. The above study indicates that finite element modeling is properly able to simulate the behaviour and strength of SCC beam under flexure. The Comparison study showed that the FEA predicts a 10% variation in the deflection studies.
