resistance curves

Resistance curves are graphical tools used to show how the strength or toughness of a material changes as it undergoes deformation, typically with increasing load or crack growth. They help engineers understand how a material responds to stress and how resistant it is to crack propagation or failure. The curve illustrates the energy needed to cause damage, guiding the assessment of safety and durability. In essence, resistance curves provide insight into a material's ability to withstand certain forces before failing, aiding in the design and maintenance of safe, reliable structures or components.
