1. Below its critical stress , the viscoelastic creep modulus is independent of stress applied. 2. Above this critical stress , the creep rate grows disproportionately faster. 3. Today, it is the critical stress intensity factor " K" 4. In fact, they are under critical stress _ at the verge of what is sustainable, 5. This critical stress can be tensile or compressive. 6. Critical stress is something people now understand.7. Twentieth-century forms of " Lebensphilosophie " can be identified with a critical stress on norms and conventions. 8. In this case, the materials fracture toughness is represented by the critical stress intensity factor K IC. 9. By analogy, the stress intensity factor, K, should be less than the critical stress intensity factor K c. 10. The critical stress which causes the growth of a microcrack of size a 0 is given by a general formula
