xjin is still having a problem:
Thanks Jan Stránský, the original problem have already been solved.
Another confusion makes me want to ask you for help.
As the explanation mentioned before, stress = (s_x, t_xy, t_xz, t_yx, s_y,
t_yz, t_zx, t_zy, s_z).
And the example I obtain:
------------------------------------------------------------------------------------------------------------------------------------------------------------
Yade [19]:obtain stress
-> [19]:
Matrix3(-0.13752527190640026,0.03607936010975411,0.0008634995770584191,
0.03445913198778846,-0.06373525199754092,0.006348443944983994,
-0.0012487034856438542,0.014427579541476804,-0.11692017375785213)
------------------------------------------------------------------------------------------------------------------------------------------------------------
Therefore,
-------------------------------------------------------------------------------------------------------------------------------------------------------------
s_x=-0.13752527190640026
t_xy=0.03607936010975411
t_xz=0.0008634995770584191
t_yx=0.03445913198778846
s_y=-0.06373525199754092
t_yz=0.006348443944983994
t_zx=-0.0012487034856438542
t_zy=0.014427579541476804
s_z=-0.11692017375785213
-------------------------------------------------------------------------------------------------------------------------------------------------------------
for the values, I find t_xy does not equal to t_yx,t_xz does not equal to t_zx
and t_yz does not equal to t_zy.
As the knowledge of Elasticity shows, the t_xy=t_yx and so on.
Is the reason that the stress calculation is approximate calculation?
Thank you!
