Standard deviation
Time
Representative volume element surrounding a point M
Mesoscopic stress tensor at a point m belonging to V(M)
Macroscopic stress tensor at point M
Local residual stress characterising the local stress in V(M)
Maximum mesoscopic shear at time t
Local equivalent stress for a life duration N,
Local equivalent stress or PSA design stress
