creep curves

Creep curves illustrate how materials slowly deform over time when subjected to a constant force or stress, especially at high temperatures. The curve typically has three stages: initially, a brief elastic deformation; then a steady, slow deformation called secondary creep; and finally, an accelerating deformation leading to failure, called tertiary creep. Understanding these curves helps predict the lifespan of materials used in high-temperature environments, like engines or bridges, ensuring safety and reliability over time.
