Abstract



In this paper, a finite element method
is formulated to solve the 2nd order Fick’s model of time dependent concentration
of semi-infinite solid in non-homogeneous materials such as concrete subjected
to chloride environment. The method formulates a time dependent problem from
the Fick’s model and proceeds to calculate the associated vectors from which
the solution can be obtained. The result obtained is highly accurate and when
compared with the exact solution and related literature tended fast to the
transient state solution.
