Strain is a measure of deformation representing the displacement between particles in a material body. It's typically expressed as a ratio and can be calculated using the following formulas:

1. Calculate Strain:

Strain (ε) is calculated by the formula:

Where:

  • is the strain (dimensionless).
  • ΔL\is the change in length (in meters).
  • L0 is the original length (in meters).

2. Calculate Change in Length from Strain:

If you know the strain and the original length, you can calculate the change in length (ΔL):

Where:

  • ΔL\ is the change in length (in meters).
  • is the strain (dimensionless).
  • L0 is the original length (in meters).

3. Calculate Original Length from Strain:

If you know the change in length and the strain, you can calculate the original length (L0 ):

Where:

  • L0 is the original length (in meters).
  • ΔL the change in length (in meters).
  • is the strain (dimensionless).
