A rectangular plate with a centrally-placed CIRCULAR hole is
extended by uniform equal forces on its Top and Bottom
surfaces, which are allowed to distort.
By reason of symmetry, only one quarter of the plate is analysed.
For calculation is used POLAR coordinates and Boundary Flow
Cells.
Comparison - a analytical solution (Timoshenko )
Boundary Condition:
===================
V ( UR) :
---------
Y = RO : StrY = FX/2*(1-RI^2/RO^2) + FX/2*(1 + 3*RI^4/RO^4 -
4*RI^2/RO^2)*COS(2*X)
U ( UTeta) :
------------
X = 0, PI/2 : U = 0,
Y = RO : StXY = - FX/2 * (1 - 3*RI^4/RO^4 + 2*RI^2/RO^2)
*SIN(2*X)
Exact Solution:
===============
Displacements
-------------
V = FX/(2*E)* R* {(1-P) + RI^2/R^2*(1+P) + [(1 - RI^4/R^4)*(1+P)
+ 4*RI^2/R^2]*COS(2*X) }
U = -FX/(2*E)* R* [(1 + RI^4/R^4)*(1+P) + 2*RI^2/R^2*(1-P)]*
SIN(2*X)
Strains
-------
EpsY = FX/(2*E)* {(1-P) - RI^2/R^2*(1+P) + [(1+P)*(1 +
3*RI^4/R^4) - 4*RI^2/R^2]*COS(2*X)}
EpsX = FX/(2*E)* {(1-P) + RI^2/R^2*(1+P) - [(1+P)*(1 +
3*RI^4/R^4) - P * 4*RI^2/R^2]*COS(2*X)}
EpsZ = - P * FX/(2*E) * [ 2 - 4*RI^2/R^2*COS(2*X) ]
D = FX/E*(1-2*P) * [1 - 2*RI^2/R^2*COS(2*X) ]
Stress
------
StrY = FX/2*(1-RI^2/R^2) + FX/2*(1 + 3*RI^4/R^4 - 4*RI^2/R^2)*
COS(2*X)
StrX = FX/2*(1+RI^2/R^2) - FX/2*(1 + 3*RI^4/R^4)*COS(2*X)
StXY = - FX/2 * (1 - 3*RI^4/R^4 + 2*RI^2/R^2)*SIN(2*X)
StrZ = 0
