Think of stress as bending or pushing down upon an object, where as strain is more like stretching a rubber-band almost to its limit, or the stress of a bridge holding up.

Stainless Steel 316 properties - Tensile Yield Strength (.2% offset): 276 MPa / 40 kpsi Ultimate Tensile Strength: 621 MPa / 90 kpsi Not sure which you're looking for, so both in case. Yield strength uses the slope of the initial elastic region of the stress-strain graph to determine a 0.2% offset along the curve; ultimate tensile strength is essentially the maximum stress experienced along the stress-strain curve.
There are a lot of test to be performed to get enough data for the research. Tensile test, hardness test, etc. Discovering the Yield Point, the Elastic and Plastic Deformation and the Fail Points on the Stress-Strain Curve. All the data is carefully collected and analyzed...
Repetitive Strain Injury
i think it depends on WHERE you explain it and WHO you explain it to.
The expression for the energy density in terms of stress and strain can be expressed as ρe.
Stress describes the intensity of loading and is defined by Force/Area. Think of it in terms of, this piece of concrete has a strength of 25N/mm2 ie each mm2 can carry up to 25N of load. Strain is a deformation due to loading and is defined as (change in length)/original length
In physics, stress is the force applied to a material, while strain is the resulting deformation or change in shape. The relationship between stress and strain in materials is explained by the concept of elasticity, which describes how materials respond to stress by deforming and returning to their original shape when the stress is removed. This relationship is typically represented by a stress-strain curve, which shows how a material deforms under different levels of stress.

Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
To calculate strain energy in a material, you can use the formula: Strain Energy 0.5 x Stress x Strain. Stress is the force applied to the material, and strain is the resulting deformation. Multiply stress and strain, then divide by 2 to find the strain energy.
To calculate strain from stress, you can use the formula: Strain Stress / Young's Modulus. Stress is the force applied to an object, while Young's Modulus is a measure of the stiffness of the material. By dividing the stress by the Young's Modulus, you can determine the strain, which is the amount of deformation the material undergoes in response to the stress.
To find strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Young's Modulus is a measure of the stiffness of a material. By dividing the stress applied to the material by its Young's Modulus, you can calculate the resulting strain.
stress is load per unit area; when an object is loaded it is under stress and strain and it stretches (strains) until it breaks at its ultimate strength. Stress i srelated to strain in the elastic region by Hooke's law: stress = elastic modulus times strain where modulus is a property of the material and strain is deflection over length
stress is directly proportional to strain up to the proportional limit. Their ratio is young's modulus.
The strain gage indicates strain, and the stress is from Hooke's law; stress = modulus times strain so you need to know the modulus of elasticity
