5.2 I-shaped specimen
To compare the accuracy of the proposed model on the prediction of the
crack path and load-displacement behavior, a tensile test on the
I-shaped specimen with the geometric properties and boundary conditions
shown in Table 3-I have been analyzed. The bottom edge is restrained
vertically and displaced horizontally, whereas the left edge is fixed.
The displacement boundary condition is applied to the right edge. The
material parameters are those of Material I in Table 1. A uniform mesh
with \(12230\ \)quadrilateral elements is used.
