Based on the theory explained in previous posts, I intend to solve a simple example.
In the element, $E$=210Gpa, $v$=0.25, $t$=20mm, ${u_1}$=0, ${v_1}$=0.05mm, ${u_2}$=0.025mm, ${v_v}$=0, ${u_3}$=0, and ${v_3}$=0.05mm.
For an element as described above, $\beta $, $\gamma $ are as follows.
Through this, the $B$ matrix can be obtained.
Knowing the area, $D$ can be calculated as follows.
Therefore,
The stress can be calculated as follows.
Therefore, it can determined as follows.
