Is strain size independent?

Stress and strain: These are size-independent measures of load and displacement, respectively.

What is relationship between stress and strain?

Hooke’s law explains the relationship between stress and strain. According to Hooke’s law, the strain in a solid is proportional to the applied stress and this should be within the elastic limit of that solid.

Is stress an independent or dependent variable?

In a scientific experiment, you cannot have a dependent variable without an independent variable. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.

What is independent stress?

Independent pronouns, listed in Table 1 , may stand alone or follow a verb or a preposition. They are used to emphasize a fact and to highlight or replace nouns or pronouns.

What is a stress variable?

Stress state variables describe the state of equilibrium of a system. When one or more stress state variables are changed, the system will change in response to establish the new equilibrium state. Hence, stress state variables are the building blocks of a constitutive relation.

What is the difference between stress and stress-strain?

Strain is the independent variable whereas stress is dependent on the amount of strain induced in the material. Stress = Young’s Modulus x Strain. The usual convention is to plot the graph with the independent variable in the X-RAY and the dependent variable on the Y-axis. This can also be noticed in the Stress-Strain diagram.

What is the slope of the stress-strain diagram?

The slope of the straight-line portion of the stress-strain diagram is called the Modulus of Elasticityor Young’s Modulus. E = σ/ε (normal stress – strain) G = τ/γ (shear stress – strain)

What is the relation between stress and strain for elastic body?

Relation between stress and strain for elastic body according to Hook’s law stress is proptional to strain. Ans: According to Hooke’s law in elasticity, “ within elastic limit,stress is directly propertional to strain.” Or, stress=k*strain , where k is called as constant of elasticity.

What does strain mean?

Hence, it is the state of strain which causes stress i.e. strain is an independent variable and stress is the dependent variable. Hooke’s Law -> [math]\\sigma \\propto \\epsilon[/math] Strain (independent variable) on the x-axis.
