$1.$ The required steps, process, and$/$or diagrams are specified below. They must be clearly shown as specified.

Creative a finite element model$/$mesh for the two$-$dimensional cracked plate shown in Fig. $1.$ You may use the constant strain triangular $($CST$)$ elements and the bilinear rectangular $($Q$4)$ elements to maximize the effectiveness of the model. Draw your model$/$mesh$.$ Replace supports and loads accordingly. Explain your considerations and comment on the accuracy of the model considering the following:

$-$ Type of Elements

$-$ Size of Elements

$-$ Location of Nodes

$-$ Number of Elements

$-$ Boundary Conditions

$-$ Loading Equivalency
