For the plane strain elements shown in Figure P6–10, the
nodal displacements are given as
u
1
= 0:005 mm v
1
= 0:002 mm u
2
= 0:0 mm
v
2
= 0:0 mm u
3
= 0:005 mm v
3
= 0:0 mm
Determine the element stresses s

.
Let E = 70 GPa and n = 0:3, and use unit thickness for plane strain. All
coordinates are in millimeters.
