WitrynaToughness. Toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of toughness (for high-strain rate, fracture toughness) is that it is a property that is indicative of a material’s resistance to fracture when a crack (or other stress-concentrating defects) is present. WitrynaAccording to the experimental findings, the addition of steel, PP, and PVA fibers improved the fc and ff. Additionally, it was discovered that the hybrid effects of SF-PP hybrid fiber-reinforced concrete and Steel-PVA hybrid fiber-reinforced concrete significantly increased the impact toughness of these materials.
