Numerical Modelling of Foamed Concrete Beam under Flexural Using Traction-Separation Relationship

The aim of the current project is to carry out FEA framework for predicting flexural strength notched foam concrete tested under three-point bending following conducted experimental set-up. investigated testing series have a variation notch size opening in foamed beam. Traction-separation relationship was used as constitutive model incorporate independent material properties and modelling framework. Modelling techniques 2D XFEM CZM were adopted later expanded 3D models. Good agreement found between predicted structure response observation all Crack initiated at crack tip propagated beam edge applied load. It that average discrepancies below 20% within techniques. Less using models, partly due simplification failure path. implemented this potentially predictive tool estimating with notches.
