Numerical investigation of the influence of casting techniques on fiber orientation distribution in ECC

Abstract Engineered cementitious composites (ECC), also known as bendable concrete, were developed based on engineering the interactions between fibers and matrix. The orientation of fibers, in this regard, is one major factors influencing ductile behavior material. In study, fiber distributions ECC beams influenced by different casting techniques are evaluated via numerical modeling process. Two directions two positions funnel outlet with beam specimens modeled using a particle-based smoothed particle hydrodynamics (SPH) method. SPH approach, fresh mortar discretized separated particles, which smoothly interact computational domain SPH. movement particles monitored during simulation. Then, orientations at sections determined after stops flowing formwork. simulation results show significant impact direction along longitudinal wall beams, eventually influence flexural strength beams. addition, negligible influences distribution short beam, except under pouring position.
