how to know good product from stress analysis?

[dannyjuniarko]

hi i have a question. i was design something and i can't read report from stress analysis. please help me to explain about  :

-Von Mises Stress,

-Principal Stress,

-3rd Principal Stress,

-Displacement,

-Safety Factor,

-Stress XX , 

-Stress XY,

-Stress XZ , 

-Stress YY , 

-Stress YZ , 

-Stress ZZ , 

-X Displacement , 

-Y Displacement,

-Z Displacement,

-Equivalent Strain,

-1st Principal Strain,

-3rd Principal Strain , 

-Strain XX , 

-Strain XY,

-Strain XZ , 

-Strain YY ,

-Strain YZ , 

-Strain ZZ, 

-Contact Pressure, 

-Contact Pressure X,

-Contact Pressure Y , 

-Contact Pressure Z

from result data, What really affects the body resistant to force? thanks before.

That's a pretty tall order.  Books have been written on the subject.  Here's a good starting point though:

http://help.autodesk.com/view/INVNTOR/2015/ENU/?guid=GUID-68384EEE-E554-4376-8674-F555F60CF7D6

In similar fashion the basic explination for what you describe can be found below:

Von Mises: Is an equivelant stress which combines the various components of the stress of the component (IE bending, shear, etc) into a single output.  This would be the 'total' stress that the component is under.  http://en.wikipedia.org/w/index.php?title=Von_Mises_yield_criterion&redirect=no

1st Principle: Is the maximum stress the component sees when the shear plane is taken into account (IE where shear is 0).  See the above help file as linked

3rd Principle: Is the minimum stress the component sees when the shear plane is taken into account (IE where shear is 0)  See the above help file as linked

Displacement: Is the total displacement in all directions--really a magnitude of the displacment of the x-, y-, and z- directions. See the above help file as linked

Safety Facotr: Is either the ultimate Tensile strength or Yield criteria set for the material compared to the von mises stress.  The result is a unitless number that will tell you, effectively, if it will fail or not.  See the above help file

Stress_xx:  Is the amount of stress perpendicular to the X-axis of the component.  See the above help file

Stress_yy:  Is the amount of stress perpendicular to the Y-axis of the component.  See the above help file

Stress_zz:  Is the amount of stress perpendicular to the Z-axis of the component.  See the above help file

Stress_xy:  Is the amount of shear stress acting in the XY-plane of the component. See the above help file

Stress_yz:  Is the amount of shear stress acting in the YZ-plane of the component.  See the above help file

Stress_xz:  Is the amount of shear stress acting in the XZ-plane of the component. See the above help file

X Displacement:  Is the displacement of the component in the X direction. See the above help file

Y Displacement: Is the displacement of the component in the Y direction. See the above help file

Z Displacement: Is the displacment of the component in the Z direction. See the above help file

Strain: Similar to stress but for strain.

Contact Pressure: Similar to displacement, but engenered more towards the interface pressure between components (ie how much force acting on an area between components).  See above help file.
