Home assignment $3-$ Finite element analysis with plane elements

In the figure, we can see the geometry, loads and constraints of a planar plate. The roller supports inhibits the motion

in the direction perpendicular to the walls. The load of the plate is a pressure of p$,$ the thickness of the plate is t$.$ The

material of the plate is described by an elastic modulus E$=180$GPa and a Poisson ratio v$=0\mathrm{.}4.$ The plate is assumed

to be in plane stress state. Based on the personal task code, the data of the task can be found in the following table:

Build the finite element model of the structure by using rectangular plane stress elements!

Determine the displacement of the nodes!

Calculate the reaction forces!

Determine the stress components and the HMH equivalent stresss at the centre of element $1!$

Plot the deformed shape of the plate!

Plot the contour diagrams of the HMH equivalent stress and the magnitude Delta of the displacement. Determine the

maximum values of these quantities in the plate!

Check your results by using Ansys!

Fill the tables!

My figure is $1,$

Code$2$ is $4$

Code$3$ is $3$

Code$4$ is $1.$

Please solve this for me$.$
