Basquin's law

Basquin's law describes how the durability of a material decreases as the load applied to it increases. Specifically, it states that the number of cycles a material can withstand before failure is inversely proportional to the stress level raised to a specific power. In simple terms, higher stresses lead to fewer cycles before failure, and this relationship is predictable using a mathematical equation. This law helps engineers estimate how long materials like metals or composites will last under repeated loading, ensuring safety and reliability in designs such as bridges, aircraft, and machinery.
