The coupled Finite Fracture Mechanics (FFM) criteria are applied to investigate the ductile failure initiation at blunt U-notched and V-notched plates under mode I loading conditions. The FFM approaches are based on the simultaneous fulfillment of the energy balance and a stress requirement. and they involve two material properties. namely the fracture toughness and the tensile strength. https://www.tipsfromatypicalmom.com/product-category/fiesta-valentine/
