Modeling of interfaces in two-dimensional problems using solid finite elements with high aspect ratio

► Modeling thin interface with solid finite elements with very high aspect ratio. ► A scalar damage model can be used to describe bond degradation due to slip. ► The technique can model the bond-slip behavior of rebars embedded in concrete. ► Densification of the finite elements in the interface region is not required. ► Discrete constitutive relations and contact elements are not necessary.
