STEP 0: Pre-Calculation Summary

Formula Used

Thermal Strain = Prevented Extension/Initial Length
ε = ΔL/l₀
This formula uses 3 Variables

Variables Used

Thermal Strain - The Thermal Strain refers to the deformation or change in dimensions experienced by a material due to changes in temperature.
Prevented Extension - (Measured in Meter) - Prevented Extension is the amount of elongation that a material would undergo due to thermal expansion, but is constrained from happening by supports, constraints, or rigid attachments.
Initial Length - (Measured in Meter) - Initial Length is the original, unaltered length of a bar or material before any changes, such as thermal expansion or contraction, occur.

STEP 1: Convert Input(s) to Base Unit

< Thermal Stress Calculators

Actual Strain when Support Yields

Go Actual Strain = (Coefficient of Linear Expansion*Change in Temperature*Length of Bar-Yield Amount (Length))/Length of Bar

Actual Expansion when Support Yields

Go Actual Expansion = Coefficient of Linear Expansion*Length of Bar*Change in Temperature-Yield Amount (Length)

Actual Stress given Support Yields for Value of Actual Strain

Go Actual Stress with Support Yield = Actual Strain*Modulus of Elasticity of Bar

Actual Strain given Support Yields for Value of Actual Expansion

Go Actual Strain = Actual Expansion/Length of Bar

< Thermal Stress and Strain Calculators

Thermal Stress given Coefficient of Linear Expansion

Go Thermal Stress given Coef. of Linear Expansion = Coefficient of Linear Expansion*Temperature Rise*Young's Modulus Bar

Thermal Strain given Coefficient of Linear Expansion

Go Thermal Strain given Coef. of Linear Expansion = Coefficient of Linear Expansion*Temperature Rise

Thermal Strain given Thermal Stress

Go Thermal Strain = Prevented Extension/Initial Length

Thermal Strain Formula

Thermal Strain = Prevented Extension/Initial Length
ε = ΔL/l₀

What is Thermal Strain?

The Thermal Strain is the strain induced due to temperature. It is also called temperature strain. The Thermal strain can be found by dividing the extension prevented by the original length.

What is Strain?

Strain is defined as the ratio of change in length due to the corresponding stress to the original length of a body.

How to Calculate Thermal Strain?

Thermal Strain calculator uses Thermal Strain = Prevented Extension/Initial Length to calculate the Thermal Strain, The Thermal Strain formula is defined as the measure of the strain produced in a material due to a change in its temperature. Thermal Strain is denoted by ε symbol.
