## Comments

1. For npg = 0 or 1, this reduces to the list of plastic strain values from the first point to the nb_integrth one.
2. Values of Epsp are given in sequence Line 4 in the following order:
• For each Integration point through the thickness j=1, nb_integr
• For each surface quadrature point i=1,npg
• Input $\text{ε}$ pi,j
