I think you are refering to the 'section modulus' which is a geometrical property of a cross section. it is the moment of inertia divided by the distance from the centroid or neutral axis to the farthest point of the section. this modulus measures flexural resistance.
It deals with one physical property sensed as elasticity.
Stress is the deforming force per unit area and strain is the proportionate change produced.
The ratio of the stress applied to the strian produced is defined as the modulus of elasticity.
There are three kinds
1. Linear-length wise
2. Bulk-volume wise
3. Shear- shape wise
This question is often inquired.
Young's modulus is one of modulus of elasticity in tension.
Young's modulus is important property to caluculate thermal expansion in horizontal direction of PCB.
It is difined as the proportional constant of Hooke's law(E=T/e)
- E =T/e
- E is Young's Modulus,
- T is stress ,
- e is stress
- Flexural modulus is defined as three points of flexural test.
- E = L3F/4bh3Y. E is flexural modulus,
- L is distance of fulcrum to fulcrum,
- b is sample width,
- h is sample thickness,
- F is load at linear part and Y is flexure at F.
- Flexural strength is defined as three points of flexural test.
- D = 3FL/2bh3. D is flexural strength,
- F is maxmum load,
- L is distance of fulcrum to fulcrum,
- b is sample width
- h is sample thickness.
- The unit of Young's modulus, flexural modulus and flexural strength is MPa.

Is tensile modulus the same as young's modulus?
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
What is the flexural modulus of aluminum?
Young`s modulus of aluminum is about 70 GPa, or 10.3 x 106 psi.
What is the relation between elastic modulus and tensile modulus?
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
What is the types of modulus of elasticity?
1. Young's modulus of elasticity, E, also called elastic modulus in tension 2. Flexural modulus, usually the same as the elastic modulus for uniform isotropic materials 3. Shear modulus, also known as modulus of rigidity, G ; G = E/2/(1 + u) for isotropic materials, where u = poisson ratio 4. Dynamic modulus 5. Storage modulus 6. Bulk modulus The first three are most commonly used; the last three are for more specialized use
What is the Young's modulus of brick?
It is the tensile stregth of brick determined from a flexural test.
What is the flexural modulus of mild steel?
what is the flexural modulus value od mild steel
Is tensile modulus the same as young's modulus?
Yes, indeed. Sometimes tensile modulus is different from flexural modulus, especially for composites. But tensile modulus and elastic modulus and Young's modulus are equivalent terms.
Is flexural modulus the same as bending stiffness?
It is related. Flexural modulus is the modulus of elasticity (E) in bending and the higher it is the higher the bending stiffness. Technically, bending stiffness is the product of the flexural modulus and the material bending moment of inertia, I, that is EI.
What is the flexural modulus of aluminum?
Young`s modulus of aluminum is about 70 GPa, or 10.3 x 106 psi.
What is the relation between elastic modulus and tensile modulus?
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.
What is elastic modulus of shale?
The elastic modulus of shale is between 1-70 GPa
What is the types of modulus of elasticity?

Bulk modulus The first three are most commonly used; the last three are for more specialized use
What is the difference between deformation modulus and Young's modulus?
Young Modulus is the slope of the stress-strain diagram in the linear elastic region. This is the most common use of modulus. As the material goes non-linear in the stress strain curve, thre slope will get increasingly lower. In this case one connects the end points of the stress strain diagram at the point of interest with a straight line. The slope of that straight line is the secant modulus.
Is young's modulus storage modulus?
The Young modulus and storage modulus measure two different things and use different formulas. A storage modulus measures the stored energy in a vibrating elastic material. The Young modulus measures the stress to in still elastic, and it is an elastic modulus.
Relation between elastic constsnt?
Elastic constants refer to the physical properties that characterize the elastic behavior of materials, such as Young's modulus, shear modulus, and bulk modulus. These constants are interrelated mathematically and are used to describe how materials respond to external forces by deforming elastically. Understanding the relationship between elastic constants is crucial in predicting the mechanical behavior of materials under different loading conditions.
What is the effect of elastic modulas on sound?
Elastic modulus affects the speed of sound propagation in a material. Materials with higher elastic modulus values transmit sound waves faster than those with lower elastic modulus values. Essentially, the higher the elastic modulus, the faster sound travels through the material.
What is the Young's modulus of brick?
It is the tensile stregth of brick determined from a flexural test.
