What are other names for bending stress?

Click For Summary
SUMMARY

The discussion centers on identifying the correct terminology for bending stress in a materials database. The user is utilizing the engineers' theory of bending, specifically the equation M/I = E/R = o/y, with given values such as a bending moment of 11.408 Nm and Young's modulus of 6828 x 10^10 pascals. It is clarified that bending stress is not synonymous with yield strength or tensile strength, but rather the maximum bending stress a material can withstand, which aligns with tensile strength when under tension.

PREREQUISITES
  • Understanding of bending stress and its significance in materials science
  • Familiarity with the engineers' theory of bending
  • Knowledge of Young's modulus and its application in stress calculations
  • Basic concepts of tensile strength and yield strength
NEXT STEPS
  • Research the relationship between bending stress and tensile strength in materials
  • Study the engineers' theory of bending in detail, focusing on the equations M/I = E/R = o/y
  • Explore materials databases to understand how bending stress is categorized
  • Learn about the calculation of moment of inertia (I) in beam theory
USEFUL FOR

Engineers, materials scientists, and students studying structural mechanics who need to understand the terminology and calculations related to bending stress in materials.

Hello, I need to input the bending stress from a database I am not sure what name it is, would it be yield strength or tensile strength? thanks

A stress is not a strength.
Please post full details of the problem.

Hello,

I am using the engineers theory of bending M/I = E/R =o/y

I have M = bending moment 11.408 Nm
I = unknown
E= 6828*10^10 pascals
R=unknown
o=in materials database
y=perpendicular distance of a point in the beam from its neutral axis, the beam is .124m long with a vertical load from the centre so I think this value is 0.062m

So I was planning to use R=o/YR to find R

then with R I can use I=E/MR

So I believe I have all the given values I am told the bending stress is in the database that's where I am to find it, I have a list youngs modulus specific stiffness yield strength tensile strength specific strength and other values,

So I'm stuck on what the name of bending stress is meant to be in the database to continue working values out.
 
Sounds like you want the maximum bending stress the material can withstand. If the component is under tension then this would be the same as the tensile strength.
