SUMMARY
The calculation of the factor of safety (FoS) using the ratio of strain (fail) to strain (allow) is valid only when the applied load is linearly related to the stress developed in the material, as described by Hooke's Law. If the relationship is nonlinear, this method becomes invalid. Additionally, the factor of safety can also be calculated using the ratio of stress (fail) to stress (allow), and these two ratios are equivalent in the linear regime where stress and strain are directly proportional.
