BEAM188/189 when used with /eshape,1 will plot total
stresses, and strains.
What is not mentioned in this thread is PRSSOL command.
That will provide the print output.
The etable quanities are "generalized stresses", i.e.,
axial force, bending moments, torque etc.
Thanks

Hi
You are right. But as no. of sections increases, this becomes very difficult
as section modulus changes. Also we will not get stress plot. Only bending
values will be there. So is there any other method to solve this problem.
Thanx in advance

Hi,
yes, bending stress data is not available in etable for beam188
elements.
but we can get bending moment using etable then using APDL code we can find
bending stress.
etable,bm,smisc,2
than we can find out
max. bending stress= bm/ "moment of inertia" *thickness
