True strain Solution

Follow our step by step solution on how to calculate True strain?

FIRST Step Consider the formula

ϵ T = \ln (\frac{l i}{L 0})

Next Step Substitute values of Variables

∴

ϵ T = \ln (\frac{2cm}{5000mm})

Next Step Convert Units

∴

ϵ T = \ln (\frac{0.02m}{5m})

Next Step Prepare to Evaluate

∴

ϵ T = \ln (\frac{0.02}{5})

Next Step Evaluate

∴

ϵ T = -5.52146091786225

LAST Step Rounding Answer

∴

ϵ T = -5.5215
