Translaminar Cracking Modeling in Woven-ply
WebOct 25, 2024 · The use of steel fiber reinforced concrete (SFRC) benefits the concrete to have enhanced strength, toughness, and ductility. To correctly model the SFRC, the fracture energy and tensile strength are the key parameters. These parameters are usually governed by the volumetric fiber content of the steel fiber to the concrete volume. WebThe CT translaminar fracture processes are divided into matrix cracking due to stress concentration, which first appears around the crack tip, and under tensile loading, where the increase in tension generates the interfacial fracture between fiber/matrix until the energy concentration is sufficient to break the fiber, as shown in Fig. 6 a [89 ... tdy moving \\u0026 storage
