Numerical modelling of the fracture of polyolefin fibre reinforced concrete by using a cohesive fracture approach

The recent generation of polyolefin-based macro-synthetic fibres have shown to meet the requirements of the standards for structural use. Therefore, polyolefin fibres have become an attractive alternative to steel reinforcement in both forms of fibres and bars. The main advantages of polyolefin fibres rely on chemical stability and lower weights for analogous reinforcements. However, the constitutive models proposed for structural design issues...
