The Theory of Critical Distances to perform the static assessment of 3D-printed concrete weakened by manufacturing defects and cracks
نویسندگان
چکیده
The Theory of Critical Distances groups together a number approaches postulating that, in cracked/notched materials subjected to static loading, breakage takes place as soon critical length-dependent effective stress exceeds the material tensile strength. characteristic length used by is property that can directly be estimated from ultimate strength and plane strain fracture toughness. In present investigation, based on large bespoke experimental results, it demonstrated successful also quantifying detrimental effect cracks manufacturing defects 3D-printed concrete Mode I loading.
