4. Summary and Concluding RemarksIn practice, cracked concrete structures sometimes experience mixed-mode loading combining tensile and shearing modes (types I and II). Motivated by this, many SCB tests have been carried out under this mixed-mode loading condition to study concrete fracturing behavior. Many earlier studies were focused on either tensile (type I) loading or this mixed-mode loading condition by using a straight-through notch in pre-cracked concrete specimens.
