Notch sensitivity refers to the degree to which the presence of a notch or geometric discontinuity in a material affects its mechanical strength and fatigue life. It is crucial in engineering design as it helps predict potential failure points and informs the selection of materials and structural shapes to enhance durability and safety.

Fatigue life is the number of stress cycles a material can endure before failure occurs, typically due to the gradual accumulation of damage under cyclic loading. It is a critical factor in engineering design, particularly for components subjected to repeated stress or strain over time.

Engineering design is a systematic and iterative process that transforms a set of requirements into a functional and optimized product or system. It involves problem-solving, creativity, and the application of scientific principles to meet specified needs while considering constraints such as cost, safety, and environmental impact.

Safety is the condition of being protected from harm or other non-desirable outcomes, often achieved through preventive measures and risk management. It encompasses a wide range of disciplines, including engineering, psychology, and public health, to ensure the well-being of individuals and communities.
