Shear stress in a shaft..
Shear stress in a shaft..
(OP)
Hi all,
I am doing gear test rig design. My problem is to find the shear stress in a stepped shaft. I have modelled with beam4 (line element). I have searched in Element table for plotting the shear stress. But couldn't get. Is there other ways to see the shear pattern in a shaft? Thanks in advance.

model the shaft 3D using small angle of rotation say 5 or 10 degrees, set the coordinate system to cylindrical, do an "nrotate", all" command
apply symmetical BC on cut surfaces, isolate line, select nodes attached to line, make component of node set, list the nodes and determine number of nodes, apply force on nodes to create torque on shaft, apply restraint on area , run, get results by setting "DSYS,#"(cylindrical coordinate system number)to get shear stress in cylindrical coordinates.

I would suggest you to use beam44, if you wanna do it in 1D. I havnt check but you can turn on the element shape /ESHAPE and plot the stresses. Try this
