User subroutine to define initial conditions for hardening variables ${\bar{ε}}^{p l}$ and $α$ .

Problem description

User subroutine HARDINI is used to define initial conditions for the hardening variables ${\bar{ε}}^{p l}$ and $α$ . These initial conditions are used to solve for the mechanical response of an M3D4 element with rebar in uniaxial tension. The problem definition is the same as in the verification file mplchi3nt1.inp (Rate-independent plasticity), where the initial conditions are specified. This input file verifies that initial conditions are assigned correctly using user subroutine HARDINI.

Results and discussion

The results match the verified results of mplchi3nt1.inp.
