Introduction to Norton-Bailey Creep Rate

The creep rate, represented as ε̇, is commonly used to estimate the deformation over time under a constant stress at high temperatures. The Norton-Bailey law is a phenomenological relation that describes creep behavior with three material constants: A, n, and Q. Here, σ represents the applied stress, n is the stress exponent, Q is the activation energy for creep, R is the gas constant, and T is the absolute temperature.

Data Validation

Both the stress and temperature should be greater than zero. Material constants A, n, and Q are needed to compute the actual creep rate.

Summary

This calculator is designed to provide an interface for the calculation of creep rate using the Norton-Bailey law, but requires the user to input specific material constants to get a quantitative result.
