Thermal Strain Solution

Follow our step by step solution on how to calculate Thermal Strain?

FIRST Step Consider the formula

ε = \frac{ΔL}{l 0}

Next Step Substitute values of Variables

∴

ε = \frac{1000mm}{5000mm}

Next Step Convert Units

∴

ε = \frac{1m}{5m}

Next Step Prepare to Evaluate

∴

ε = \frac{1}{5}

LAST Step Evaluate

∴

ε = 0.2

The Thermal Strain refers to the deformation or change in dimensions experienced by a material due to changes in temperature.

Symbol: ε

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Thermal Strain

Prevented Extension

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.

Symbol: ΔL

Measurement: LengthUnit: mm

Note: Value can be positive or negative.

Formulas to find Prevented Extension

Initial Length

Initial Length is the original, unaltered length of a bar or material before any changes, such as thermal expansion or contraction, occur.

Symbol: l₀

Measurement: LengthUnit: mm

Note: Value should be greater than 0.
