Shear Strain

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Shear strain, abbreviated as $$\gamma$$ (Greek symbol gamma), a dimensionless number, (measured in radians), is opposing forces acting parrallel to the cross-section of a body.

Shear strain formula

 $$\large{ \gamma = \frac{ \Delta y }{ l_i } }$$

Where:

 Units English Metric $$\large{ \gamma }$$  (Greek symbol gamma) = shear strain $$\large{deg}$$ $$\large{rad}$$ $$\large{ l_i }$$ = initial length $$\large{ in }$$ $$\large{ mm }$$ $$\large{ \Delta y }$$ = transverse displacement $$\large{ in }$$ $$\large{ mm }$$
