stress-strain calculations
(OP)
See the attached file.
I have conducted a pull test with loadings as per the attached file. P, M, L, and area of the sample are known, and Strain was obtained in the testing.
Axial stress is obtained by using P/A. Is there any way I can calculate the bending stress due to M?
Thanks.

RE: stress-strain calculations
y is distance away from neutral axis
I area moment of inertia of cross section
Euler-Bernoulli bending theory
RE: stress-strain calculations
c is the distance from the centerline to the furthest longi. edge.
I is the are moment of inertia.
If its a 'pure' moment it can be replaced by a couple.
Although, I am not exactly sure this is what you want.

Is there a way, using the measured strain only, to estimate the bending stress? This is part of a product development project, and I want to compare the estimated stress against my initial calculated stress.
RE: stress-strain calculations
stress/strain = E
do the math ...
RE: stress-strain calculations
stress/strain = E is what I needed.
